Name of the Vulnerable Software and Affected Versions: Nagios Fusion versions 4.1.8 and earlier

Description: The issue allows for privilege escalation to root via modification of scripts. Low-privilege users can modify files that can be executed by sudo, which enables them to gain elevated access.

As a temporary workaround, consider restricting access to the scripts that can be executed by sudo to minimize the risk of exploitation.
