All Links in Two Topics of Indiatimes (indiatimes.com) Are Vulnerable to XSS (Cross Site Scripting) Attacks


All Links in Two Topics of Indiatimes (indiatimes.com) Are Vulnerable to XSS (Cross Site Scripting) Attacks 



(1) Domain Description:
http://www.indiatimes.com



"The Times of India (TOI) is an Indian English-language daily newspaper. It is the third-largest newspaper in India by circulation and largest selling English-language daily in the world according to Audit Bureau of Circulations (India). According to the Indian Readership Survey (IRS) 2012, the Times of India is the most widely read English newspaper in India with a readership of 7.643 million. This ranks the Times of India as the top English daily in India by readership. It is owned and published by Bennett, Coleman & Co. Ltd. which is owned by the Sahu Jain family. In the Brand Trust Report 2012, Times of India was ranked 88th among India's most trusted brands and subsequently, according to the Brand Trust Report 2013, Times of India was ranked 100th among India's most trusted brands. In 2014 however, Times of India was ranked 174th among India's most trusted brands according to the Brand Trust Report 2014, a study conducted by Trust Research Advisory." (en.Wikipedia.org)





(2) Vulnerability description:
The web application indiatimes.com online website has a security problem. Hacker can exploit it by XSS bugs.

The code flaw occurs at Indiatimes's URL links. Indiatimes only filter part of the filenames in its website. All URLs under Indiatimes's "photogallery" and "top-llists" topics are affected. 

Indiatimes uses part of the links under "photogallery" and "top-llists" topics to construct its website content without any checking of those links at all. This mistake is very popular in nowaday websites. Developer is not security expert.


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





POC Codes:

POC Video:






What is XSS?
"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." (OWASP)





(3) Vulnerability Disclosure:
The vulnerabilities were reported to Indiatimes in early September, 2014. However they are still unpatched.

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/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.

GetPocket getpocket.com CSRF (Cross-Site Request Forgery ) Web Security Vulnerability











GetPocket getpocket.com CSRF (Cross-Site Request Forgery ) Web Security Vulnerability

Domain: getpocket.com
"Pocket was founded in 2007 by Nate Weiner to help people save interesting articles, videos and more from the web for later enjoyment. Once saved to Pocket, the list of content is visible on any device — phone, tablet or computer. It can be viewed while waiting in line, on the couch, during commutes or travel — even offline. The world's leading save-for-later service currently has more than 17 million registered users and is integrated into more than 1500 apps including Flipboard, Twitter and Zite. It is available for major devices and platforms including iPad, iPhone, Android, Mac, Kindle Fire, Kobo, Google Chrome, Safari, Firefox, Opera and Windows." (From: https://getpocket.com/about)


Vulnerability Description:
Pocket has a computer cyber security bug problem. Hacker can exploit it by CSRF attacks.

 "Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application." (OWSAP)


Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2)，Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.



Vulnerability Details:
The code programming flaw exists at "https://getpocket.com/edit/edit" page, i.e.https://getpocket.com/edit?url=http%3A%2F%2Fwpshout.com%2Fchange-wordpress-theme-external-php&title=

Vulnerable URL:
https://getpocket.com/edit?url=http%3A%2F%2Fwpshout.com%2Fchange-wordpress-theme-external-php&title=


Use a website created by me for the following tests. The website is "http://itinfotech.tumblr.com/". Suppose that this website is malicious. If it contains the following link, attackers can post any message as they like.
<a href="https://getpocket.com/edit?url=http%3A%2F%2Fmake.wordpress.org%2Fcore%2F2014%2F01%2F15%2Fgit-mirrors-for-wordpress&title=csrf test">getpocket csrf test</a> [1]


When a logged victim clicks the link ([1]), a new item will be successfully saved to his/her "Pocket" without his/her notice. An attack happens.

CNN Travel.cnn.com XSS and Ads.cnn.com Open Redirect Web Security Vulnerabilities


















CNN Travel.cnn.com XSS and Ads.cnn.com Open Redirect Web Security Vulnerabilities



Domain:
http://cnn.com


"The Cable News Network (CNN) is an American basic cable and satellite television channel that is owned by the Turner Broadcasting System division of Time Warner. The 24-hour cable news channel was founded in 1980 by American media proprietor Ted Turner. Upon its launch, CNN was the first television channel to provide 24-hour news coverage, and was the first all-news television channel in the United States. While the news channel has numerous affiliates, CNN primarily broadcasts from the Time Warner Center in New York City, and studios in Washington, D.C. and Los Angeles, its headquarters at the CNN Center in Atlanta is only used for weekend programming. CNN is sometimes referred to as CNN/U.S. to distinguish the American channel from its international sister network, CNN International. As of August 2010, CNN is available in over 100 million U.S. households. Broadcast coverage of the U.S. channel extends to over 890,000 American hotel rooms, as well as carriage on cable and satellite providers throughout Canada. Globally, CNN programming airs through CNN International, which can be seen by viewers in over 212 countries and territories. As of February 2015, CNN is available to approximately 96,289,000 cable, satellite and, telco television households (82.7% of households with at least one television set) in the United States."

Vulnerability Description:

CNN has a cyber security bug problem. It cab be exploited by XSS (Cross Site Scripting) and Open Redirect (Unvalidated Redirects and Forwards) attacks.

Based on news published, CNN users were hacked based on both Open Redirect and XSS vulnerabilities.

According to E Hacker News on June 06, 2013, (@BreakTheSec) came across a diet spam campaign that leverages the open redirect vulnerability in one of the top News organization CNN.

After the attack, CNN takes measures to detect Open Redirect vulnerabilities. The measure is quite good during the tests. Almost no links are vulnerable to Open Redirect attack on CNN's website, now. It takes long time to find a new Open Redirect vulnerability that is un-patched on its website.

CNN.com was hacked by Open Redirect in 2013. While the XSS attacks happened in 2007.



<1> "The tweet apparently shows cyber criminals managed to leverage the open redirect security flaw in the CNN to redirect twitter users to the Diet spam websites."























Figure from ehackingnews.com





At the same time, the cybercriminals have also leveraged a similar vulnerability in a Yahoo domain to trick users into thinking that the links point to a trusted website.

(1) CNN (cnn.com) Travel-City Related Links XSS (cross site scripting) Web Security Bugs



Domain:
travel.cnn.com/



Vulnerability Description:

The programming bug flaws occur at "/city/all" pages. All links under this URL are vulnerable to XSS attacks, e.g




XSS 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. Base on Acunetix, exploited XSS is commonly used to achieve the following malicious results
  • Identity theft
  • Accessing sensitive or restricted information
  • Gaining free access to otherwise paid for content
  • Spying on user’s web browsing habits
  • Altering browser functionality
  • Public defamation of an individual or corporation
  • Web application defacement
  • Denial of Service attacks


The code programming flaw can be exploited without user login. Tests were performed on Firefox (34.0) in Ubuntu (14.04) and IE (9.0.15) in Windows 7.

(2) CNN cnn.com ADS Open Redirect Web Security Bug


Domain:
ads.cnn.com


Vulnerability Description:

The programming code flaw occurs at "event.ng" page with "&Redirect" parameter, i.e.


From OWASP, an open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it. 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.


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

The redirected webpage address is "http://webcabinet.tumblr.com/". Suppose that this webpage is malicious.



Vulnerable URL:

POC:

Since CNN is well-known worldwide, this vulnerability can be used to do "Covert Redirect" attacks to other websites.
