AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions MantisBT versions prior to 2.25.2

Description The issue is related to a lack of protection of the web page structure in the manage custom field edit page.php component of the MantisBT bug tracking system. This allows a remote attacker to perform cross-site scripting attacks. The unescaped output of the return parameter enables an attacker to inject code into a hidden input field.

Recommendations For versions prior to 2.25.2, update to version 2.25.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the manage custom field edit page.php component until a patch is available. Avoid using the return parameter in the affected component until the issue is resolved.
