FKIE_CVE-2011-10035

Vulnerability from fkie_nvd - Published: 2025-10-30 22:15 - Updated: 2026-06-16 23:28
Summary
Nagios XI versions prior to 2011R1.9 contain privilege escalation vulnerabilities in the scripts that install or update system crontab entries. Due to time-of-check/time-of-use race conditions and missing synchronization or final-path validation, a local low-privileged user could manipulate filesystem state during crontab installation to influence the files or commands executed with elevated privileges, resulting in execution with higher privileges.
