CVE-2020-36868: nagios xi (CVSS 7.8)

Description

Nagios XI versions prior to 5.7.3 contain a privilege escalation vulnerability in the getprofile.sh helper script. The script performed profile retrieval and initialization routines using insecure file/command handling and insufficient validation of attacker-controlled inputs, and in some deployments executed with elevated privileges. A local attacker with low-level access could exploit these weaknesses to cause the script to execute arbitrary commands or modify privileged files, resulting in privilege escalation.
