Michael Brooks has discovered some vulnerabilities in Profense Web Application Firewall, which can be exploited by malicious people to conduct cross-site scripting and cross-site request forgery attacks.
1) Input passed via the "proxy" parameter in proxy.html is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) The application allows users to perform certain actions via HTTP requests without performing any validity check to verify the request. This can be exploited to perform certain actions, e.g. to shutdown the system, by enticing a logged-in administrator to visit a malicious web site.
The vulnerability is reported in version 2.6.2 and confirmed in version 2.6.3. Other versions may also be affected.
Solution: Update to version 2.6.4.
