CVE-2022-3979

Name of the Vulnerable Software and Affected Versions NagVis versions up to 1.9.33

Description A vulnerability was found in the function checkAuthCookie of the file share/server/core/classes/CoreLogonMultisite.php. The manipulation of the argument hash leads to incorrect type conversion. The attack may be initiated remotely. The complexity of an attack is rather high, and the exploitation is known to be difficult.
