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.

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.
