The two printed papers currently are run separately with different editorial staff, but there is cross-usage of stories. News articles published in either, plus online Telegraph articles, may also be published on the Telegraph Media Group's www.telegraph.co.uk website, all under The Telegraph title." (From Wikipedia)




(1) Vulnerability Description:
Telegraph has a Web security bug problem. It is vulnerable to XSS attacks. In fact, all its photo pages are vulnerable to XSS (Cross-Site Scripting) vulnerabilities. Telegraph's picture pages use "&frame" as its parameter. All its web pages use "&frame" are vulnerable to the bugs. Those vulnerabilities have been patched now.


Examples of Vulnerable Links:



POC Code:


The vulnerability can be attacked without user login. Tests were performed on Firefox (37.02) in Ubuntu (14.04) and IE (8.0. 7601) in Windows 7. The bugs found by using CSXDS.


































































 







(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."

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/)>


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 Weather Channel at Least 76.3% Links Vulnerable to XSS Attacks

The Weather Channel at Least 76.3% Links Vulnerable to XSS Attacks




Domain Description:
http://www.weather.com/




"The Weather Channel is an American basic cable and satellite television channel which broadcasts weather forecasts and weather-related news and analyses, along with documentaries and entertainment programming related to weather.  Launched on May 2, 1982, the channel broadcasts weather forecasts and weather-related news and analysis, along with documentaries and entertainment programming related to weather."

"As of February 2015, The Weather Channel was received by approximately 97.3 million American households that subscribe to a pay television service (83.6% of U.S. households with at least one television set), which gave it the highest national distribution of any U.S. cable channel. However, it was subsequently dropped by Verizon FiOS (losing its approximately 5.5 millions subscribers), giving the title of most distributed network to HLN. Actual viewership of the channel averaged 210,000 during 2013 and has been declining for several years. Content from The Weather Channel is available for purchase from the NBCUniversal Archives." (Wikipedia)




Vulnerability description:


The Weather Channel has a cyber security problem. Hacker can exploit it by XSS bugs.


Almost all links under the domain weather.com are vulnerable to XSS attacks. Attackers just need to add script at the end of The Weather Channel's URLs. Then the scripts will be executed.


10 thousands of Links were tested based a self-written tool. During the tests, 76.3% of links belong to weather.com were vulnerable to XSS attacks.


The reason of this vulnerability is that Weather Channel uses URLs to construct its HTML tags without filtering malicious script codes. 




The vulnerability can be attacked without user login. Tests were performed on Firefox (34.0) in Ubuntu (14.04) and IE (9.0.15) in Windows 8.



















POC Codes, e.g.
http://www.weather.com/slideshows/main/"--/>"><img src=x onerror=prompt('justqdjing')>
http://www.weather.com/home-garden/home/white-house-lawns-20140316%22--/"--/>"><img src=x onerror=prompt('justqdjing')>t%28%27justqdjing%27%29%3E
http://www.weather.com/news/main/"><img src=x onerror=prompt('justqdjing')>







POC Video:






The Weather Channel has patched this Vulnerability in late November, 2014 (last Week).  "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!" A great many of 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. This bug was published at The Full Disclosure in November, 2014.
