Name of the Vulnerable Software and Affected Versions: Thruk versions 2.40 through 2

Description: The issue allows for Reflected XSS via the host or title parameter in the "/thruk/#cgi-bin/status.cgi" endpoint. An attacker could inject arbitrary JavaScript into status.cgi, which would be triggered every time an authenticated user browses the page containing it.

Recommendations: For Thruk versions 2.40 through 2, as a temporary workaround, consider restricting access to the "/thruk/#cgi-bin/status.cgi" endpoint until a patch is available. Avoid using the host or title parameters in this endpoint to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
