(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) ASP Version: 6kbbs (6k Forum) is an excellent community forum process . The program is simple but not simple ; fast , small ; interface generous and good scalability ; functional and practical . pursue superiority , good interface , practical functions of choice for subscribers."



(2) Vulnerability Details:
6kbbs web application has a computer security problem. It can be exploited by weak encryption attacks. The software stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. A weak encryption scheme can be subjected to brute force attacks that have a reasonable chance of succeeding using current attack methods and resources.
Several 6kbbs products 0-day web cyber bugs have been found by some other bug hunter researchers before. 6kbbs 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 web securities have been published here.


Source Code:
<?php
if(empty($row)){
        $extrow=$db->row_select_one("users","username='{$username}'");
        if(!empty($extrow) && !empty($extrow['salt'])){
                if(md5(md5($userpass).$extrow['salt'])==$extrow['userpass']){
                        $row=$extrow;
                        $new_row["userpass"]=$userpass_encrypt;
                        $new_row["salt"]="";
                        $db->row_update("users",$new_row,"id={$extrow['id']}");
                }
        }
}
?>

Source Code From:
http://code.google.com/p/6kbbs/source/browse/trunk/convert/discuz72/loginext.php?r=16
We can see that "userpass" stored in cookie was encrypted using "$userpass" user password directly. And there is no "HttpOnly" attribute at all. Since md5 is used for the encryption, it is easy for hackers to break the encrypted message.
"The MD5 message-digest cryptography algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number. Papers about it have been published on Eurocrypt, Asiacrypt and Crypto. Meanwhile, researchers focusing on it spread in Computer Science, Computer Engineering, IEEE and Mathematics. MD5 has been utilized in a wide variety of cryptographic applications, and is also commonly used to verify data integrity. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4. The source code in RFC 1321 contains a "by attribution" RSA license." (Wikipedia)

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.

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.

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

(1.1) Domain Description:

"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)

(1.3) 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.
