Daily mail Registration Page Unvalidated Redirects and Forwards & XSS Web Security Problem

 

Website Description:
“The Daily Mail is a British daily middle-market tabloid newspaper owned by the Daily Mail and General Trust. First published in 1896 by Lord Northcliffe, it is the United Kingdom’s second biggest-selling daily newspaper after The Sun. Its sister paper The Mail on Sunday was launched in 1982. Scottish and Irish editions of the daily paper were launched in 1947 and 2006 respectively. The Daily Mail was Britain’s first daily newspaper aimed at the newly-literate “lower-middle class market resulting from mass education, combining a low retail price with plenty of competitions, prizes and promotional gimmicks”, and was the first British paper to sell a million copies a day. It was at the outset a newspaper for women, the first to provide features especially for them, and as of the second-half of 2013 had a 54.77% female readership, the only British newspaper whose female readers constitute more than 50% of its demographic. It had an average daily circulation of 1,708,006 copies in March 2014. Between July and December 2013 it had an average daily readership of approximately 3.951 million, of whom approximately 2.503 million were in the ABC1 demographic and 1.448 million in the C2DE demographic. Its website has more than 100 million unique visitors per month.” (Wikipedia)

One of its website’s Alexa rank is 93 on January 01 2015. The website is one of the most popular websites in the United Kingdom.

The Unvalidated Redirects and Forwards problem has not been patched, while the XSS problem has been patched.

 

 

 

(1) Daily mail Registration Page Unvalidated Redirects and Forwards Web Security Problem

 

(1.1) Vulnerability Description:
Daily online websites have a cyber security problem. Hacker can exploit it by Open Redirect (Unvalidated Redirects and Forwards) attacks. During the tests, all Daily mail websites (Daily Mail, Mail on Sunday & Metro media group) use the same mechanism. These websites include dailymail.co.uk, thisismoney.co.uk, and mailonsunday.co.uk.

 

 

dailymail_1

thisismoney_1

 

 

 

Google Dork:
“Part of the Daily Mail, The Mail on Sunday & Metro Media Group”

 

 

The vulnerability occurs at “&targetUrl” parameter in “logout.html?” page, i.e.
http://www.dailymail.co.uk/registration/logout.html?targetUrl=http%3A%2F%2Fgoogle.com

 

 

 

(1.2.1) Use the following tests to illustrate the scenario painted above.

The redirected webpage address is “http://diebiyi.com/articles“. Can suppose that this webpage is malicious.

 

 

 

(1.2.2) The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 8, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2),and Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

These bugs were found by using URFDS (Unvalidated Redirects and Forwards Detection System).

 

 

 

(1.2) Description of Open Redirect:
Here is the description of Open Redirect: “A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. An http parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts have a more trustworthy appearance.” (From CWE)

 

 

 

(1.3) Vulnerability Disclosure:
These vulnerabilities have not been patched.

 

 

 

 

(2) Daily Mail Website XSS Cyber Security Zero-Day Vulnerability

(2.1) Vulnerability description:
DailyMail has a security problem. Criminals can exploit it by XSS attacks.

The vulnerability occurs at “reportAbuseInComment.html?” page with “&commentId” parameter, i.e.
http://www.dailymail.co.uk/home/reportAbuseInComment.html?articleId=346288&commentId=877038

The vulnerability can be attacked without user login. Tests were performed on Mozilla Firefox (34.0) in Ubuntu (14.04) and Microsoft IE (9.0.15) in Windows 7.

(2.2) What is XSS?
“Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side script into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy. Cross-site scripting carried out on websites accounted for roughly 84% of all security vulnerabilities documented by Symantec as of 2007. Their effect may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site and the nature of any security mitigation implemented by the site’s owner.” (Wikipedia)

 

 

 

(2.3) Vulnerability Disclosure:
This vulnerability has been patched.

(2) XSS Description:

The description of XSS is: “Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted web sites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it.” (OWSAP)

The New York Times(Nytimes.com) Covert Redirect Web Security Bug Based on Google Doubleclick.net

New-York-Times-office

(1) WebSite:

nytimes.com



“The New York Times (NYT) is an American daily newspaper, founded and continuously published in New York City since September 18, 1851, by the New York Times Company. It has won 117 Pulitzer Prizes, more than any other news organization.

The paper’s print version has the largest circulation of any metropolitan newspaper in the United States, and the second-largest circulation overall, behind The Wall Street Journal. It is ranked 39th in the world by circulation. Following industry trends, its weekday circulation has fallen to fewer than one million daily since 1990. Nicknamed for years as “The Gray Lady”, The New York Times is long regarded within the industry as a national “newspaper of record”. It is owned by The New York Times Company. Arthur Ochs Sulzberger, Jr., (whose family (Ochs-Sulzberger) has controlled the paper for five generations, since 1896), is both the paper’s publisher and the company’s chairman. Its international version, formerly the International Herald Tribune, is now called the International New York Times.” (Wikipedia)

(2) Vulnerability Description:

The New York Times web application has a computer cyber security problem. Hacker can exploit it by Covert Redirect 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 programming code flaw occurs at “adx_click.html?” page with “&goto” parameter, i.e.

http://www.nytimes.com/adx/bin/adx_click.html?type=goto&opzn&page=www.nytimes.com/pages/nyregion/index.html&pos=SFMiddle&sn2=8dfce1f6/9926f9b3&sn1=bbba504f/c0de9221&camp=CouplesResorts_1918341&ad=NYRegionSF_Feb_300x250-B5732328.10663001&goto=http%3A%2F%2Fad%2Edoubleclick%2Enet%2Fddm%2Fclk%2F279541164%3B106630011%3Bs%3Fhttp%3A%2F%2Ffacebook%2Ecom%2Fall%2Dinclusive%2Ephp%3Futm%5Fsource%3Dnyt%26utm%5Fmedium%3Ddisplay%26utm%5Fcontent%3Dclicktracker%26utm%5Fcampaign%3D300x250%5FExpectMore%5FNYT%5FNYRegion

(2.1) When a user is redirected from Nytimes to another site, Nytimes will check parameters “&sn1″ and “&sn2″. If the redirected URL’s domain is OK, Nytimes will allow the reidrection.

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from Nytimes 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 Nytimes directly.

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

(2.2) Use one of webpages for the following tests. The webpage address is “http://xingti.tumblr.com”. 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. Hacker may use it to steal users’ sensitive information. 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.

It is headquartered in San Jose, California. eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. Today, it is a multi-billion dollar business with operations localized in over thirty countries.

 

The company manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a broad variety of goods and services worldwide. In addition to its auction-style sales, the website has since expanded to include “Buy It Now” shopping; shopping by UPC, ISBN, or other kind of SKU (via Half.com); online classified advertisements (via Kijiji or eBay Classifieds); online event ticket trading (via StubHub); online money transfers (via PayPal) and other services.” (Wikipedia)

 



(2) Vulnerability Description:

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

The vulnerability occurs at “ebay.com/rover” page with “&mpre” parameter, i.e.

http://rover.ebay.com/rover/1/711-67261-24966-0/2?mtid=691&kwid=1&crlp=1_263602&itemid=370825182102&mpre=http://www.google.com

The vulnerability can be attacked without user login. Tests were performed on Firefox (26.0) in Ubuntu (12.04) and IE (9.0.15) in Windows 7.


 

 

 

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

 

One of the vulnerable domain is,
http://googleads.g.doubleclick.net (Google’s Ad system)

 

 

 

(2.2) Use one of webpages for the following tests. The webpage address is “http://itinfotech.tumblr.com/“. 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. Hacker may use it to steal users’ sensitive information. 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.

(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)

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.
