Product Introduction Overview:
"Your search to find the best photo gallery has led you to the most feature rich, best performing, and most widely used gallery available today. PhotoPost is the best way to offer your users the ability to upload, show off, share, discuss, and rate photos and videos on your site. We originally created PhotoPost in 2001 for TechIMO.com, our parent company's own tech discussion website with 2 Million forum posts and 200,000 users, and within weeks we were inundated with requests, so we decided to develop it into a product. Over the past 8 years, PhotoPost has undergone more than 100 "dot" updates by a team of expert developers to add features, tweak performance, and maximize stability. Always in high demand, PhotoPost has been purchased by a staggering 14,500 websites. PhotoPost is most popular amongst vBulletin forum owners. That's because we designed PhotoPost from the beginning to integrate efficiently with a website's existing vBulletin forum, offering users one integrated login and registration instead of two, stylesheet integration, and other enhancements. But what PhotoPost does well for vBulletin owners, it does equally well for those that wish to integrate a gallery with many other forum types, or to simply add a photo gallery to their website with no forum at all. "










(2) Vulnerability Details:
PhotoPost PHP web application has a computer security problem. Hackers can exploit it by XSS cyber attacks. This 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.

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. PhotoPost PHP has patched some of them. CXSECurity is a huge collection of information on data communications safety. Its main objective is to inform about errors in various applications. It also publishes suggestions, advisories, solutions details related to XSS vulnerabilities and cyber intelligence recommendations.



(2.1) The code flaw occurs at "|utmcct" parameter in "__utmz" Cookie.


For example, if a victim clicks the link below.
http://localhost/gallery/showphoto.php/photo/846/sort/'"><marquee><h1>test</h1></marquee><svg/onload=prompt(/tetraph/)>


The content of "__utmz" cookie will be the following:
__utma 194200300.1295483682.1438243020.1438243020.1438245659.2
__utmc 194200300
__utmz 194200300.1438243020.1.1.utmccn=(referral)|utmcsr=mgs-on-track.com|utmcct=/gallery/showphoto.php/photo/846/sort/1%27%22%3E%3Cimg%20src=x%20onerror=alert%28%27tetraph%27%29%3E%3Cmarquee%3E%3Ch1%3Etest%3C/h1%3E%3C/marquee%3E|utmcmd=referral
__qca P0-814178849-1438243024810
__utmb 194200300
bbsessionhash 1683dd3bd3edffbd8383db382f025eba
bblastvisit 1438246612


So the malicious code can work in the user's browser for long time.





(2.2) Forum Integrations
"PhotoPost can optionally integrate as an add-on to an existing forum on your site, and we do this extremely well. PhotoPost is a perfect fit with a forum, because sharing and discussing photos within PhotoPost comes naturally for a forum community.

With our forum integration, your users will use their existing forum account to login to PhotoPost, without needing to register again and maintain a separate account. Additionally, we offer stylesheet integrations with several forums to easily setup your PhotoPost gallery to match your forum's look and feel, and with vBulletin 3.x we offer several additional enhancements."

(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) 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.

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)
