It can be exploited by stored 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 other MT.VERNON MEDIA products 0-day vulnerabilities have been found by some other bug hunter researchers before. MT.VERNON MEDIA has patched some of them. BugScan is the first community-based scanner, experienced five code refactoring. It has redefined the concept of the scanner provides sources for the latest info-sec news, tools, and advisories. It also publishs suggestions, advisories, solutions details related to HTML vulnerabilities. *(2.1) *The first programming code flaw occurs at "&category" parameter in "gallery.php?" page. *References:* http://www.tetraph.com/security/html-injection/mt-vernon-media-web-design-v1-12-html-injection/ http://securityrelated.blogspot.com/2015/05/mtvernon-media-web-design-v112-html.html http://www.inzeed.com/kaleidoscope/computer-web-security/mt-vernon-media-web-design-v1-12-html-injection/ https://vulnerabilitypost.wordpress.com/2015/05/08/mt-vernon-media-web-design-v1-12-html-injection/ http://whitehatpost.blog.163.com/blog/static/24223205420154893850881/ https://progressive-comp.com/?l=full-disclosure&m=142907520526783&w=2 https://www.bugscan.net/#!/x/21454 http://seclists.org/fulldisclosure/2015/Apr/37 http://lists.openwall.net/full-disclosure/2015/04/15/3 -- Jing Wang, Division of Mathematical Sciences (MAS), School of Physical and Mathematical Sciences (SPMS), Nanyang Technological University (NTU), Singapore. http://www.tetraph.com/wangjing/ https://twitter.com/justqdjing
