Bypass Google Open Redirect Filter Based on Googleads.g.doubleclick.net

— Google Covert Redirect Vulnerability Based on Googleads.g.doubleclick.net

 

 

 

(1) WebSite:
google.com

 

“Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results.

 

The corporation has been estimated to run more than one million servers in data centers around the world (as of 2007). It processes over one billion search requests and about 24 petabytes of user-generated data each day (as of 2009). In December 2013, Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger. Its market dominance has led to prominent media coverage, including criticism of the company over issues such as search neutrality, copyright, censorship, and privacy.” (Wikipedia)

 

 

 

 

(2) Vulnerability Description:

Google web application has a computer cyber security problem. Hacker can exploit it by Covert Redirect attacks. 

The vulnerability exists at “Logout?” page with “&continue” parameter, i.e.

 
 


The vulnerabilities can be attacked without user login. Tests were performed on Microsoft IE (10.0.9200.16750) of Windows 8, Mozilla Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04)，Apple Safari 6.1.6 of Mac OS X Lion 10.7. 

 
 
 
 
 
 (2.1) When a user is redirected from Google to another site, Google will check whether the redirected URL belongs to domains in Google’s whitelist (The whitelist usually contains websites belong to Google), e.g.
docs.google.com
googleads.g.doubleclick.net

 
 
 

 

If this is true, the redirection will be allowed.

 

 

However, if the URLs in a redirected domain have open URL redirection  vulnerabilities themselves, a user could be redirected from Google to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site. This is as if being redirected from Google directly.

 

 

One of the vulnerable domain is,
googleads.g.doubleclick.net (Google’s Ad System)

 
 
 
 

 

 

 

(2.2) Use one webpage for the following tests. The webpage address is “http://www.inzeed.com/kaleidoscope“. We can suppose that this webpage is malicious.

(3) What is Covert Redirect? 

Covert Redirect is a class of security bugs disclosed in May 2014. It is an application that takes a parameter and redirects a user to the parameter value without sufficient validation. This often makes use of Open Redirect and XSS vulnerabilities in third-party applications.

 

Covert Redirect is also related to single sign-on. It is known by its influence on OAuth and OpenID. Almost all OAuth 2.0 and OpenID providers worldwide are affected. Covert Redirect was found and dubbed by a Mathematics PhD student Wang Jing from School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore.

 

After Covert Redirect was published, it is kept in some common databases such as SCIP, OSVDB, Bugtraq, and X-Force. Its scipID is 13185, while OSVDB reference number is 106567. Bugtraq ID: 67196.  X-Force reference number is 93031.

(4) Alibaba Taobao（taobao.com）Covert Redirect Security Vulnerability Based on Apple.com



(4.1) Vulnerability description:

Alibaba Taobao has a security problem. It can be exploited by Covert Redirect attacks. Taobao will check whether the redirected URL belongs to domains in Taobao’s whitelist, e.g.

If this is true, the redirection will be allowed.

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from Taobao to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site. This is as if being redirected from Taobao directly.

In fact, Apple.com was found can be exploited by Open Redirect vulnerabilities. Those vulnerabilities details will be published in the near future.



(4.2) The vulnerability occurs at “redirect.htm?” page, with parameter “&url”, i.e.

The vulnerabilities can be attacked without user login. Tests were performed on IE (10.0) of Windows 8, Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04)，Safari 6.1.6 of Mac OS X Lion 10.7.

 

 

(4.3) Use a website for the tests，the redirected webpage is “http://www.tetraph.com/blog“. Just suppose it is malicious.

Facebook Old Generated URLs Still Vulnerable to Open Redirect Attacks & A New Open Redirect Web Security Bugs




Domain:
http://www.facebook.com



“Facebook is an online social networking service headquartered in Menlo Park, California. Its website was launched on February 4, 2004, by Mark Zuckerberg with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. The founders had initially limited the website’s membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Since 2006, anyone who is at least 13 years old is allowed to become a registered user of the website, though the age requirement may be higher depending on applicable local laws. Its name comes from a colloquialism for the directory given to it by American universities students.” (Wikipedia)



“Facebook had over 1.44 billion monthly active users as of March 2015.Because of the large volume of data users submit to the service, Facebook has come under scrutiny for their privacy policies. Facebook, Inc. held its initial public offering in February 2012 and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. As of February 2015 Facebook reached a market capitalization of $212 Billion.” (Wikipedia)

(1) General Vulnerabilities Description:

(1.1) Two Facebook vulnerabilities are introduced in this article.

Facebook has a computer cyber security bug problem. It can be exploited by Open Redirect attacks. This could allow a user to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker’s choosing. Such attacks are useful as the crafted URL initially appear to be a web page of a trusted site. This could be leveraged to direct an unsuspecting user to a web page containing attacks that target client side software such as a web browser or document rendering programs.


Since Facebook is trusted by large numbers of other websites. Those vulnerabilities can be used to do “Covert Redirect” to other websites such as Amazon, eBay, Go-daddy, Yahoo, 163, Mail.ru etc.

 

(1.1.1)

One Facebook Open Redirect vulnerability was reported to Facebook. Facebook adopted a new mechanism to patch it. Though the reported URL redirection vulnerabilities are patched. However, all old generated URLs are still vulnerable to the attacks. Section (2) gives detail of it.

The reason may be related to Facebook’s third-party interaction system or database management system or both. Another reason may be related to Facebook’s design for different kind of browsers.

 

(1.1.2) Another new Open Redirect vulnerability related to Facebook is introduced, too. For reference, please read section (3).

The vulnerabilities can be attacked without user login. Tests were performed on IE (9.0) of Windows 8, Firefox (24.0) & Google Chromium 30.0.1599.114 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (12.10)，Safari 6.1.6 of Mac OS X Lion 10.7.



(1.2) Facebook’s URL Redirection System Related to “*.php” Files

All URLs’ redirection are based on several files, such l.php, a.php, landing.php and so on.

The main redirection are based on file “l.php” (Almost all redirection links are using it right now).

For file “l.php”, one parameter “h” is used for authentication. When it mentions to file “a.php”, parameter “eid” is used for authentication. All those two files use parameter “u” for the url redirected to. In some other files such as “landing.php”, parameters such as “url”, “next” are used.

<1>For parameter “h”, two forms of authentication are used.

<a>h=HAQHyinFq

<b>h=hAQHalW1CAQHrkVIQNNqgwhxRWLNsFVeH3auuImlbR1CgKA

<2>For parameter “eid”, one form of authentication is used.

<a>eid=AQLP8sRq6lbU0jz0lARx9A9uetB6FIF1N2-Yjj_ePj0d_ezubjstZeDo6qDsalKVJwy6uDb_hQ-9tBsA2dVoQRq0lniOu0os_gPe3gY5l8lYblhQSwBtdvgjXjNqaxLZMYoasr3vv46tFsh1fL7q4kjT2LFw52dnJWd4SE8qc0YuPWfgPeQywgM2wl0CoW-lftWkr2dX0dLcytyHjXnvhKfVS_pQBllszUzsPENxE6EuZ-53Lh188o56idnfyyk2L58pE7C94PF-za4ZVB0qbuA2EnPcSJI-7oIiIJmIhifHe0CYTzG512-Z_heN44VlyJHevhS9auAR8-lFCAIlYymnT_Qiwp92RxjNOfBypBvszQUrvB6PH3fANn1prfMBVm4RD_GFel14KVDS5USswbTOTkL3sZNhHUqqPHwBwU3JFePMMuwsfesigH85B_AxCsXUIWN7klKGSq8bPPsKSHttsa9hkkMpSfRKL7D_xwW4dU2xlmfGWil7jYRJmwfbOeF0zujk1FRBuM757tbfFMav-J-K9npbdrDrCuUVqV__Tf7CGZ89nPl-M2d09pE9enJj0OBXOaSXZX16LKaYnv1Wh4GKme7C-EOunITxyQtp1zy-48Uaz9mxO2x4bw7sBDfzDStF_Al8_0SMjWNTh-J38rBHAgT96X-dPFI43HU3x3fVymE9szrclBpvTaSfYezatgMzf77s3lQrQAMSlwSSRIzRuoFvQBmWKT0T5ZFgH5ykhYKhNMiKj577UO5g2Ojm-_-KKF4N_DBuG5R-I6EOSlhok2xUkpKVDnDcxZFTLxGmx5xc56J5kZLjJ96wnF2fH09Q19Qc2aU3xYFlEFrKjrlLpwGyOyCDx7_z7y1O4Efqew3Fa0Cb9s6Kk2jpLF5XEIaYzzXOLAffxXG6icBJVovb9RPmiZ5s9dKYYotLol68_X04O05bEvVccPEh-IQwX_VTMt3f23be2MECEqR2l1A1ZkJx4qP00GI1pZhU_CXAnjSaTNmtaINRUeSsLNEZZsPwpWJMfeeGSwuof9krC05eSWjO0jH9tua0KteMYhj8i-3dwSBp4f7nMcFwH5ltfCLhMCYNB8rxgzcAczyhLIo2UY-3FSaJXBZ0lvuZBvnj7myUnyc2lCcy-fWh93MRRaJrrinjtfr9fDSMHM9Cja5xi0eG3Vs0aClnWbeJZA79TvmYt7E53HfwGuv5-EJOqRh3cwZF-53uPHA73ikUk3xTApjQunJM4uIBhpy7iBIgn_OXXo3X03YUJtJcDuC20ocJbZ310VHliox5tYZF2oiMaOfgo9Y9KeqgsrJgwPCJeif4aB0Ne4g_oM_Tuqt2pXbdgoCawHIApF087eFKJqejp0jpEkJerXPyK-IqsD_SQfIm_2WJSkzwzATwQKs

 

 

 


(2) Vulnerability Description 1:

Those vulnerabilities were reported to Facebook in 2014 and they have been patched.





Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. Facebook has patched some of them. “The Full Disclosure mailing list is a public forum for detailed discussion of vulnerabilities and exploitation techniques, as well as tools, papers, news, and events of interest to the community. FD differs from other security lists in its open nature and support for researchers’ right to decide how to disclose their own discovered bugs. The full disclosure movement has been credited with forcing vendors to better secure their products and to publicly acknowledge and fix flaws rather than hide them. Vendor legal intimidation and censorship attempts are not tolerated here!” All the fllowing web securities have been published here, Buffer overflow, HTTP Response Splitting (CRLF), CMD Injection, SQL injection, Phishing, Cross-site scripting, CSRF, Cyber-attack, Unvalidated Redirects and Forwards, Information Leakage, Denial of Service, File Inclusion, Weak Encryption, Privilege Escalation, Directory Traversal, HTML Injection, Spam. Large number of Facebook bugs were published here. FD also publishes suggestions, advisories, solutions details related to Open Redirect vulnerabilities and cyber intelligence recommendations.








(4) Amazon Covert Redirect Security Vulnerability Based on Facebook

Since Facebook is trusted by large numbers of other websites. Those vulnerabilities can be used to do “Covert Redirect” to other websites such as Amazon.


Domain:
http://www.amazon.com


“American electronic commerce company with headquarters in Seattle, Washington. It is the largest Internet-based retailer in the United States. Amazon.com started as an online bookstore, but soon diversified, selling DVDs, Blu-rays, CDs, video downloads/streaming, MP3 downloads/streaming, software, video games, electronics, apparel, furniture, food, toys and jewelry. The company also produces consumer electronics—notably, Amazon Kindle e-book readers, Fire tablets, Fire TV and Fire Phone — and is a major provider of cloud computing services. Amazon also sells certain low-end products like USB cables under its inhouse brand AmazonBasics. Amazon has separate retail websites for United States, United Kingdom & Ireland, France, Canada, Germany, The Netherlands, Italy, Spain, Australia, Brazil, Japan, China, India and Mexico. Amazon also offers international shipping to certain other countries for some of its products. In 2011, it had professed an intention to launch its websites in Poland and Sweden.” (Wikipedia)

 

 

The vulnerability exists at “redirect.html?” page with “&location” parameter, e.g.

 

(4.1) When a user is redirected from Amazon to another site, Amazon will check parameters “&token”. If the redirected URL’s domain is OK, Amazon will allow the reidrection.

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from Amazon to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site. This is as if being redirected from Amazon directly.

One of the vulnerable domain is,
http://www.facebook.com

 

(4.2) Use one of webpages for the following tests. The webpage address is “http://www.inzeed.com/kaleidoscope“. Suppose it is malicious.

Godaddy Online Website Covert Redirect Web Security Bugs Based on Google.com

 

(1) Domain:
godaddy.com

 

 

“GoDaddy is a publicly traded Internet domain registrar and web hosting company. As of 2014, GoDaddy was said to have had more than 59 million domain names under management, making it the world’s largest ICANN-accredited registrar. It serves more than 12 million customers and employs more than 4,000 people. The company is known for its celebrity spokespeople, Super Bowl ads and as being an online provider for small businesses. In addition to a postseason college football bowl game, it sponsors NASCAR. It has been involved in several controversies related to security and privacy. In addition to domain registration and hosting, GoDaddy also sells e-business related software and services.” (Wikipedia)

 

 

 

 

 

(2) Vulnerability Description:
Godaddy web application has a computer security problem. Hacker can exploit it by Covert Redirect cyber attacks. 

 


The vulnerabilities can be attacked without user login. Tests were performed on Microsoft IE (10.0.9200.16750) of Windows 8, Mozilla Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04)，Apple Safari 6.1.6 of Mac OS X Lion 10.7. 

 

The vulnerability occurs at “redirect.aspx?” page with “&target” parameter, i.e.
http://img.godaddy.com/redirect.aspx?ci=1161&target=https%3A%2F%2Fwww.google.com

 

 

 

(2.1) When a user is redirected from Godaddy to another site, Godaddy will check whether the redirected URL belongs to domains Godaddy’s whitelist, e.g.
google.com
apple.com

 

If this is true, the redirection will be allowed.

 

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from Godaddy to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site. This is as if being redirected from Godaddy directly.

 

One of the vulnerable domain is,
google.com

 

 

 

(2.2) Use one of webpages for the following tests. The webpage address is “http://diebiyi.com/articles/“.  Can suppose that this page is malicious.

 

Vulnerable URL:
http://img.godaddy.com/redirect.aspx?ci=1161&target=https%3A%2F%2Fwww.godaddy.com

 

POC:
http://img.godaddy.com/redirect.aspx?ci=1161&target=https%3A%2F%2Fwww.google.com%2Faccounts%2FLogout%3Fservice%3Dwise%26continue%3Dhttp%253A%252F%252Fgoogleads.g.doubleclick.net%252Faclk%253Fsa%253DL%2526ai%253DCtHoIVxn3UvjLOYGKiAeelIHIBfLQnccEAAAQASAAUNTx5Pf4_____wFgvwWCARdjYS1wdWItMDQ2NjU4MjEwOTU2NjUzMsgBBOACAKgDAaoE5AFP0NHr5cHwFmWgKNs6HNTPVk7TWSV-CDHX83dKdGSWJ2ADoZNIxUHZwjAODRyDY_7nVtpuqSLOTef4xzVxDQ2U22MNbGak33Ur7i2jDB8LdYt9TbC3ifsXmklY5jl3Zpq4_lP7wagVfjt0–tNPPGTR96NGbxgPvfHMq9ZsTXpjhc_lPlnyGjlWzF8yn437iaxhGRwYLt_CymifLO2YaJPkCm9nLpONtUM-mstUSpKQrP2VjjaZkbDtuK0naLLBV37aYEY4TzWQi8fQGN47z4XgpinBCna91zQayZjn2wxccDCl0zgBAGgBhU%2526num%253D0%2526sig%253DAOD64_3Qi4qG3CRVHRI5AHSkSGuL7HJqSA%2526client%253Dca-pub-0466582109566532%2526adurl%253Dhttp%253A%252F%252Fwww.tetraph.com%252Fcontact.html

(3) What is Covert Redirect?
Covert Redirect is a class of security bugs disclosed in May 2014. It is an application that takes a parameter and redirects a user to the parameter value without sufficient validation. This often makes use of Open Redirect and XSS (Cross-site Scripting) vulnerabilities in third-party applications.

 
 Covert Redirect is also related to single sign-on, such as OAuth and OpenID. Hacker may use it to steal users’ sensitive information. Almost all OAuth 2.0 and OpenID providers worldwide are affected. Covert Redirect can work together with CSRF (Cross-site Request Forgery) as well.

Yahoo Online Service OpenID Covert Redirect Web Security Bugs (Information Leakage & Open Redirect)




(1) Domain:
yahoo.com

 

 

“Yahoo Inc. (styled as Yahoo!) is an American multinational technology company headquartered in Sunnyvale, California. It is globally known for its Web portal, search engine Yahoo Search, and related services, including Yahoo Directory, Yahoo Mail, Yahoo News, Yahoo Finance, Yahoo Groups, Yahoo Answers, advertising, online mapping, video sharing, fantasy sports and its social media website. It is one of the most popular sites in the United States. According to news sources, roughly 700 million people visit Yahoo websites every month. Yahoo itself claims it attracts “more than half a billion consumers every month in more than 30 languages.” Yahoo was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 1, 1995. Marissa Mayer, a former Google executive, serves as CEO and President of the company.” (Wikipedia)

 

 

 

 

(2) Vulnerability Description:

Yahoo web application has a computer security problem. Hacker can exploit it by Covert Redirect cyber attacks.



The vulnerabilities can be attacked without user login. Tests were performed on Microsoft IE (10.0.9200.16750) of Windows 8, Mozilla Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04)，Apple Safari 6.1.6 of Mac OS X Lion 10.7.

 


(2.1) Vulnerability Detail:

Yahoo’s OpenID system is susceptible to Attacks. More specifically, the authentication of parameter “&openid.return_to” in OpenID system is insufficient. It can be misused to design Open Redirect Attacks to Yahoo.

 

It increases the likelihood of successful Open Redirect Attacks to third-party websites, too.

 

The vulnerability was reported to Yahoo. Yahoo do not reply the report for months.

 

 

The vulnerabilities occurs at page “/openid/op/auth?” with parameter “&openid.return_to”, e.g.
https://open.login.yahooapis.com/openid/op/auth?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.return_to=http%3A%2F%2Fwww.rhogroupee.com%2FopenIdRp%3Fredirect%3Dhttp%253A%252F%252Fwww.rhogroupee.com%252Fjoin%252Fcontext%252FGENERAL%252Fredirect%252Fhttp%25253A%25252F%25252Fwww.tetraph.com%25252Fessayjeans%25252Fpoems%25252Ftree.html&openid.realm=http%3A%2F%2Fwww.rhogroupee.com%2FopenIdRp&openid.aOpenIDc_handle=J3IvS0xNnpIPn34CEn0hiEWBXYqhaV941hmD.Yx2_vv8JZk2gWSEWoOjpjKYvkNSvP3mUGcz1J1UoIIvaNWTjwMhrKyizwARZNZwooVUVGEvA9sau2DcXoMbLRuhkJ_HOS.O_w–&openid.mode=checkid_setup&openid.ns.ext1=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1&openid.ext1.optional=nickname%2Cemail%2CemailVerified%2Cdob%2Cgender%2Ccountry&openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fsreg%2F1.0&openid.sreg.optional=nickname%2Cemail%2CemailVerified%2Cdob%2Cgender%2Ccountry&openid.ns.ext3=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&openid.ext3.mode=fetch_request&openid.ext3.type.Username=http%3A%2F%2Fschema.openid.net%2FnamePerson%2Ffriendly&openid.ext3.type.Email=http%3A%2F%2Fschema.openid.net%2Fcontact%2Femail&openid.ext3.type.Birth+date=http%3A%2F%2Fschema.openid.net%2FbirthDate&openid.ext3.type.Gender=http%3A%2F%2Fschema.openid.net%2Fperson%2Fgender&openid.ext3.type.Country=http%3A%2F%2Fschema.openid.net%2Fcontact%2Fcountry%2Fhome&openid.ext3.required=Username%2CEmail%2CBirth+date%2CGender%2CCountry [1]

 

 

Before acceptance of third-party application:

 

When a logged-in Yahoo user clicks the URL ([1]) above, he/she will be asked for consent as in whether to allow a third-party website to receive his/her information. If the user clicks OK, he/she will be then redirected to the URL assigned to the parameter “&openid.return_to”.

 

If a user has not logged onto Yahoo and clicks the URL ([1]) above, the same situation will happen upon login.

 

After acceptance of third-party application:

 

A logged-in Yahoo user would no longer be asked for consent and could be redirected to a webpage controlled by the attacker when he/she clicks the URL ([1]).

 

For a user who has not logged in, the attack could still be completed after a pop-up page that prompts him/her to log in.

 

 

 

(2.1.1) Yahoo would normally allow all the URLs that belong to the domain of an authorized third-party website. However, these URLs could be prone to manipulation. For example, the “&openid.return_to” parameter in the URLs is supposed to be set by the third-party websites, but an attacker could change its value to make Attacks.

 

Hence, a user could be redirected from Yahoo to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site unwillingly. This is as if the user is redirected from Yahoo directly. The number of Yahoo’s OpenID client websites is so huge that such Attacks could be commonplace.

 

Before acceptance of the third-party application, Yahoo’s OpenID system makes the redirects appear more trustworthy and could potentially increase the likelihood of successful Open Redirect Attacks of third-party website.

 

Once the user accepts the application, the attackers could completely bypass Yahoo’s authentication system and attack more easily.

 

It might be of Yahoo’s interest to patch up against such attacks.

 

 

 

(2.2) Used one of webpages for the following tests. The webpage is “http://qianqiuxue.tumblr.com/“. Can suppose it is malicious.

 

Below is an example of a vulnerable third-party domain:
rhogroupee.com

 

 

Vulnerable URL in this domain:
http://www.rhogroupee.com/join/context/GENERAL/redirect/http%3A%2F%2Fwww.tetraph.com%2Fessayjeans%2Fpoems%2Ftree.html

 

Vulnerable URL from Yahoo that is related to rhogroupee.com:

(3) What is Covert Redirect?

Covert Redirect is a class of security bugs disclosed in May 2014. It is an application that takes a parameter and redirects a user to the parameter value without sufficient validation. This often makes use of Open Redirect and XSS (Cross-site Scripting) vulnerabilities in third-party applications.

 

Covert Redirect is also related to single sign-on. It is known by its influence on OAuth and OpenID. Hacker may use it to steal users’ sensitive information. Almost all OAuth 2.0 and OpenID providers worldwide are affected. Covert Redirect can work together with CSRF (Cross-site Request Forgery) as well. After Covert Redirect was published, it is kept in some common databases such as SCIP, OSVDB, Bugtraq, and X-Force. Its scipID is 13185, while OSVDB reference number is 106567. Bugtraq ID: 67196. X-Force reference number is 93031.
