Title: Woltlab Burning Board Misc.PHP Cross-Site Scripting Vulnerability

Severity: MODERATE

Description:

Woltlab Burning Board is a free web-based bulletin-board package based on PHP and MySQL.

Woltlab Burning Board is prone to a cross-site scripting vulnerability. This issue is due to a lack of proper sanitization of user-supplied input.

The 'percent' parameter to the 'acp/misc.php' script is not properly sanitized, allowing an attacker to submit malicious HTML and script code through a malicious URI.

An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.

Affected Products:

  • Woltlab Burning Board 2.3.4
