Last modified

CVE-2020-36868 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. 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. EPSS estimates a 0.28% chance of exploitation in the next 30 days.

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.
