(2) Vulnerability Details:

6kbbs web application has a computer cyber security bug problem. It can be exploited by CSRF (Cross-Site Request Forgery) attacks. This may allow an attacker to trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into creating files that may then be called via a separate CSRF attack or possibly other means, and executed in the context of their session with the application, without further prompting or verification.

Several 6kbbs products 0-day vulnerabilities have been found by some other bug hunter researchers before. 6kbbs has patched some of them. Open Sourced Vulnerability Database (OSVDB) is an independent and open-sourced database. The goal of the project is to provide accurate, detailed, current, and unbiased technical information on security vulnerabilities. The project promotes greater, open collaboration between companies and individuals. It has published suggestions, advisories, solutions details related to csrf vulnerabilities.

(2) Vulnerability Details:

NetCat web application has a computer security bug problem. It can be exploited by HTML Injection attacks. Hypertext Markup Language (HTML) injection, also sometimes referred to as virtual defacement, is an attack on a user made possible by an injection vulnerability in a web application. When an application does not properly handle user supplied data, an attacker can supply valid HTML, typically via a parameter value, and inject their own content into the page. This attack is typically used in conjunction with some form of social engineering, as the attack is exploiting a code-based vulnerability and a user’s trust.

Several NetCat products 0-day vulnerabilities have been found by some other bug hunter researchers before. NetCat has patched some of them. Web Security Watch is an aggregator of security reports coming from various sources. It aims to provide a single point of tracking for all publicly disclosed security issues that matter. “Its unique tagging system enables you to see a relevant set of tags associated with each security alert for a quick overview of the affected products. What’s more, you can now subscribe to an RSS feed containing the specific tags that you are interested in – you will then only receive alerts related to those tags.” It has published suggestions, advisories, solutions details related to cyber security vulnerabilities.

 

(2.1) The programming code flaw occurs at “/catalog/search.php?” page with “&q” parameter.

About Group (about.com) All Topics (At least 99.88% links) Vulnerable to XSS & Iframe Injection Security Attacks, About.com Open Redirect Web Security Vulnerabilities

Man Running in Digital Vortex --- Image by © Michael Agliolo/Corbis

About Group (about.com) All Topics (At least 99.88% links) Vulnerable to XSS & Iframe Injection Security Attacks, About.com Open Redirect Security Vulnerabilities

 

Vulnerability Description:
About.com all “topic sites” are vulnerable to XSS (Cross-Site Scripting) and Iframe Injection (Cross Frame Scripting) attacks. This means all sub-domains of about.com are affected. Based on a self-written program, 94357 links were tested. Only 118 links do not belong to the topics (Metasites) links. Meanwhile, some about.com main pages are vulnerable to XSS attack, too. This means no more than 0.125% links are not affected. At least 99.875% links of About Group are vulnerable to XSS and Iframe Injection attacks. In fact, for about.com’s structure, the main domain is something just like a cover. So, very few links belong to them.

 

Simultaneously, the About.com main page’s search field is vulnerable to XSS attacks, too. This means all domains related to about.com are vulnerable to XSS attacks.

 

 

Simultaneously, the About.com main page’s search field is vulnerable to XSS attacks, too. This means all domains related to about.com are vulnerable to XSS attacks.

 

For the Iframe Injection vulnerability. They can be used to do DDOS (Distributed Denial-of-Service Attack) to other websites, too.

Here is one example of DDOS based on Iframe Injection attacks of others.
http://www.incapsula.com/blog/world-largest-site-xss-ddos-zombies.html

 

In the last, some “Open Redirect” vulnerabilities related to about.com are introduced. There may be large number of other Open Redirect Vulnerabilities not detected. Since About.com are trusted by some the other websites. Those vulnerabilities can be used to do “Covert Redirect” to these websites.

 

 

Vulnerability Disclosure:
Those vulnerabilities were reported to About on Sunday, Oct 19, 2014. No one replied. Until now, they are still unpatched.

(1) Some Basic Background

 

“For March 2014, 61,428,000 unique visitors were registered by comScore for About.com, making it the 16th-most-visited online property for that month.” (The New York Times)

 

“About.com, also known as The About Group (formerly About Inc.), is an Internet-based network of content that publishes articles and videos about various subjects on its “topic sites,” of which there are nearly 1,000. The website competes with other online resource sites and encyclopedias, including those of the Wikimedia Foundation, and, for March 2014, 61,428,000 unique visitors were registered by comScore for About.com, making it the 16th-most-visited online property for that month. As of August 2012, About.com is the property of IAC, owner of Ask.com and numerous other online brands, and its revenue is generated by advertising.” (Wikipedia)

 

“As of May 2013, About.com was receiving about 84 million unique monthly visitors.” (TechCrunch. AOL Inc.)

 

“According to About’s online media kit, nearly 1,000 “Experts” (freelance writers) contribute to the site by writing on various topics, including healthcare and travel.” (About.com)

 

 

(1.2) Topics Related to About.com
“The Revolutionary About.com Directory and Community Metasite. Hundreds of real live passionate Guides covering Arts, Entertainment, Business, Industry, Science, Technology, Culture, Health, Fitness, Games,Travel, News, Careers, Jobs, Sports, Recreation, Parenting, Kids, Teens, Moms, Education, Computers, Hobbies and Local Information.” (azlist.about.com)

So, there are more than 1000 topics related to about.com.

 

 

(1.3) Result of Exploiting XSS Attacks
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 (DOS)

” (Acunetix)

 

 

(1.4) Basics of Iframe Injection (Cross-frame-Scripting) Vulnerabilities
“In an XFS (Cross-frame-Scripting) attack, the attacker exploits a specific cross-frame-scripting bug in a web browser to access private data on a third-party website. The attacker induces the browser user to navigate to a web page the attacker controls; the attacker’s page loads a third-party page in an HTML frame; and then JavaScript executing in the attacker’s page steals data from the third-party page.” (OWASP)

 

“XFS also sometimes is used to describe an XSS attack which uses an HTML frame in the attack. For example, an attacker might exploit a Cross Site Scripting Flaw to inject a frame into a third-party web page; or an attacker might create a page which uses a frame to load a third-party page with an XSS flaw.” (OWASP)

 

 

(1.5) Basic of Open Redirect (Dest Redirect Privilege Escalation) Vulnerabilities
“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.” (OWASP)

Open redirect is listed in OWASP top 10. The general consensus of it is “avoiding such flaws is extremely important, as they are a favorite target of phishers trying to gain the user’s trust.”

 

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. CNN has patched some of them. “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 following 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 URL Redirection vulnerabilities and cyber intelligence recommendations.

(5) About (about.com) Open Redirect Multiple (Dest Redirect Privilege Escalation) Security Vulnerabilities

About Group online web application has a computer cyber security bug problem. It can be exploited by Unvalidated Redirects and Forwards (URL Redirection) attacks. 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.

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

 

Domain:

“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)

 

Discovered and Reported by:

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.

 

 

“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.

 

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.

 

 

(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.

 

Those vulnerabilities were reported to CNN in early July by Contact from Here. But they are still not been patched yet.
