Title: Xhawk.net Discussion BBCode IMG Tag Script Injection Vulnerability
Severity: MODERATE
Description:
The 'discussion' application from xhawk.net is a web-based bulletin board.
The 'discussion' application is prone to a script-injection vulnerability. The application fails to properly sanitize user-supplied input before including it in dynamically generated content.
An attacker can use BBCode IMG tags to trigger this issue and execute arbitrary code in a user's browser.
Attacker-supplied HTML and script code would be able to access properties of the site, potentially allowing for the 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. A victim user who views the vulnerable sections of the site would have the attacker-supplied HTML and script code execute in the security context of the affected site.
Version 2.0 beta2 of 'discussion' is reportedly prone to this vulnerability.
Affected Products:
