Title: MyBB Print Thread Script HTML Injection Vulnerability
Severity: MODERATE
Description:
MyBB (MyBulletinBoard) is Web forum software implemented in PHP utilizing a MySQL backend.
MyBB is prone to an HTML injection vulnerability. This issue manifests itself when user-supplied input containing HTML and script code is viewed through the "print view of thread" feature in 'printthread.php'.
Attacker-supplied HTML and script code would be executed in the context of the affected Web site, potentially allowing for theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.
