Description:
A vulnerability has been reported in Invision Power Board, which can be exploited by malicious users to conduct Cross-Site Scripting attacks against other users.
An input validation error in "post_parser.php" can be exploited by injecting arbitrary script code in [FONT], [SIZE] and [COLOR] BBCode tags. This can be executed in another user's browser session and may disclose sensitive information (eg. cookie-based authentication information) associated with the site running Invision Power Board or inclusion of malicious content, which the user thinks is part of the real website.
The vulnerability has been reported in version 1.2 FINAL.
