**Name of the Vulnerable Software and Affected Versions** Woltlab Burning Board (wBB) version 2.3.4 **Description** A cross-site scripting (XSS) issue exists, allowing remote attackers to inject arbitrary web script or HTML via the `errormsg` parameter when a SQL error is generated. This occurs in the acp/lib/class db mysql.php file. **Recommendations** For Woltlab Burning Board (wBB) version 2.3.4, consider restricting access to the `errormsg` parameter to minimize the risk of exploitation. As a temporary workaround, avoid using the `errormsg` parameter in situations where SQL errors may be generated until a patch is available.
