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


Domain:
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." (Wikipedia)

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> There are some tweets complaining about hacked with links from CNN.

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.

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. CNN has patched some of them. BugTraq is a full disclosure moderated mailing list for the *detailed* discussion and announcement of computer security vulnerabilities: what they are, how to exploit them, and how to fix them. The below things be posted to the Bugtraq list: (a) Information on computer or network related security vulnerabilities (UNIX, Windows NT, or any other). (b) Exploit programs, scripts or detailed processes about the above. (c) Patches, workarounds, fixes. (d) Announcements, advisories or warnings. (e) Ideas, future plans or current works dealing with computer/network security. (f) Information material regarding vendor contacts and procedures. (g) Individual experiences in dealing with above vendors or security organizations. (h) Incident advisories or informational reporting. (i) New or updated security tools. A large number 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. It also publishes suggestions, advisories, solutions details related to XSS and URL Redirection vulnerabilities and cyber intelligence recommendations.

ESPN espn.go.com Login & Register Page XSS and Dest Redirect Privilege Escalation Web Security Vulnerabilities


Domain:
http://espn.go.com/


“ESPN (originally an acronym for Entertainment and Sports Programming Network) is a U.S.-based global cable and satellite television channel that is owned by ESPN Inc., a joint venture between The Walt Disney Company (which operates the network, through its 80% controlling ownership interest) and Hearst Corporation (which holds the remaining 20% interest). The channel focuses on sports-related programming including live and recorded event telecasts, sports news and talk shows, and other original programming.


ESPN broadcasts primarily from studio facilities located in Bristol, Connecticut. The network also operates offices in Miami, New York City, Seattle, Charlotte, and Los Angeles. John Skipper currently serves as president of ESPN, a position he has held since January 1, 2012. While ESPN is one of the most successful sports networks, it has been subject to criticism, which includes accusations of biased coverage, conflict of interest, and controversies with individual broadcasters and analysts. ESPN headquarters in Bristol, Connecticut. As of February 2015, ESPN is available to approximately 94,396,000 paid television households (81.1% of households with at least one television set) in the United States. In addition to the flagship channel and its seven related channels in the United States, ESPN broadcasts in more than 200 countries, operating regional channels in Australia, Brazil, Latin America and the United Kingdom, and owning a 20% interest in The Sports Network (TSN) as well as its five sister networks and NHL Network in Canada.”(Wikipedia)


Vulnerability description:
Espn.go.com has a cyber security bug problem. It is vulnerable to XSS (Cross Site Scripting) and Dest Redirect Privilege Escalation (Open Redirect) attacks.


Those vulnerabilities are very dangerous. Since they happen at ESPN’s “login” & “register” pages that are credible. Attackers can abuse those links to mislead ESPN’s users. The success rate of attacks may be high.


During the tests, besides the links given above, large number of ESPN’s links are vulnerable to those attacks.


The programming code flaw occurs at “espn.go.com”’s “login?” & “register” pages with “redirect” parameter, i.e.

http://streak.espn.go.com/en/login?redirect=

https://r.espn.go.com/members/login?appRedirect=http%3A%2F%2Fr.espn.go.com

http://games.espn.go.com/world-cup-bracket-predictor/2014/es/login?redirect=

https://register.go.com/go/sendMemberNames?regFormId=espn&appRedirect=http://register.go.com/



Tests were performed on Firefox (33.0) in Ubuntu (14.04) and IE (8.0. 7601) in Windows 8.

“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, Injection, Broken Authentication and Session Management, Cross-Site Scripting (XSS), Insecure Direct Object References, Security Misconfiguration, Sensitive Data Exposure, Missing Function Level Access Control, Cross-Site Request Forgery (CSRF), Using Components with Known Vulnerabilities, Unvalidated Redirects and Forwards. It also publishes suggestions, advisories, solutions details related to XSS and Open Redirect vulnerabilities and cyber intelligence recommendations.




(1) XSS Web Security Vulnerability
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
