CVE-2013-5983

Name of the Vulnerable Software and Affected Versions GuppY versions prior to 4.6.28

Description The issue concerns multiple cross-site scripting (XSS) vulnerabilities. These vulnerabilities allow remote attackers to inject arbitrary web script or HTML. Specifically, the vulnerabilities can be exploited via the an parameter to "agenda.php" or the cat parameter to "mobile/thread.php".

Recommendations For versions prior to 4.6.28, update to version 4.6.28 or later to resolve the issue. As a temporary workaround, consider restricting access to the "agenda.php" and "mobile/thread.php" endpoints until the update is applied. Avoid using the an and cat parameters in the affected endpoints until the issue is resolved.
