Name of the Vulnerable Software and Affected Versions OPNsense versions prior to 23.7.5

Description The issue is related to the lack of protection of the web page structure in the OPNsense operating system. This can be exploited by a remote attacker to conduct cross-site scripting attacks using the column count parameter in the "index.php" page, specifically targeting the Lobby Dashboard.

Recommendations For versions prior to 23.7.5, update to version 23.7.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the Lobby Dashboard or disabling the column count parameter in the index.php page until a patch is applied.
