Product Introduction Overview:

“Your search to find the best photo gallery has led you to the most feature rich, best performing, and most widely used gallery available today. PhotoPost is the best way to offer your users the ability to upload, show off, share, discuss, and rate photos and videos on your site. We originally created PhotoPost in 2001 for TechIMO.com, our parent company’s own tech discussion website with 2 Million forum posts and 200,000 users, and within weeks we were inundated with requests, so we decided to develop it into a product. Over the past 8 years, PhotoPost has undergone more than 100 “dot” updates by a team of expert developers to add features, tweak performance, and maximize stability. Always in high demand, PhotoPost has been purchased by a staggering 14,500 websites. PhotoPost is most popular amongst vBulletin forum owners. That’s because we designed PhotoPost from the beginning to integrate efficiently with a website’s existing vBulletin forum, offering users one integrated login and registration instead of two, stylesheet integration, and other enhancements. But what PhotoPost does well for vBulletin owners, it does equally well for those that wish to integrate a gallery with many other forum types, or to simply add a photo gallery to their website with no forum at all. ”

 

 

 

(2) Vulnerability Details:

PhotoPost PHP web application has a computer security problem. Hackers can exploit it by XSS cyber attacks. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user’s browser session within the trust relationship between their browser and the server.

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. PhotoPost PHP has patched some of them. CXSECurity is a huge collection of information on data communications safety. Its main objective is to inform about errors in various applications. It also publishes suggestions, advisories, solutions details related to XSS vulnerabilities and cyber intelligence recommendations.

 

 

(2.1) The code flaw occurs at “|utmcct” parameter in “__utmz” Cookie.

For example, if a victim clicks the link below.

http://localhost/gallery/showphoto.php/photo/846/sort/'”><marquee><h1>test</h1></marquee><svg/onload=prompt(/tetraph/)&gt;

The content of “__utmz” cookie will be the following:

__utma 194200300.1295483682.1438243020.1438243020.1438245659.2

__utmc 194200300

__utmz 194200300.1438243020.1.1.utmccn=(referral)|utmcsr=mgs-on-track.com|utmcct=/gallery/showphoto.php/photo/846/sort/1%27%22%3E%3Cimg%20src=x%20onerror=alert%28%27tetraph%27%29%3E%3Cmarquee%3E%3Ch1%3Etest%3C/h1%3E%3C/marquee%3E|utmcmd=referral

__qca P0-814178849-1438243024810

__utmb 194200300

bbsessionhash 1683dd3bd3edffbd8383db382f025eba

bblastvisit 1438246612

So the malicious code can work in the user’s browser for long time.

 

 

(2.2) Forum Integrations

“PhotoPost can optionally integrate as an add-on to an existing forum on your site, and we do this extremely well. PhotoPost is a perfect fit with a forum, because sharing and discussing photos within PhotoPost comes naturally for a forum community.

With our forum integration, your users will use their existing forum account to login to PhotoPost, without needing to register again and maintain a separate account. Additionally, we offer stylesheet integrations with several forums to easily setup your PhotoPost gallery to match your forum’s look and feel, and with vBulletin 3.x we offer several additional enhancements.”

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.

Vulnerable URL:
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

(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.

“eBay Inc. (stylized as ebay, formerly eBay) is an American multinational corporation and e-commerce company, providing consumer to consumer & business to consumer sales services via Internet. 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.
