Nagios XI versions prior to 2012R1.3 contain a SQL injection vulnerability in the legacy Core Configuration Manager (CCM) interface. Authenticated users could manipulate SQL queries by supplying crafted input to specific CCM parameters, potentially allowing access to configuration data stored in the application database. Successful exploitation could disclose or modify notification data and, in some cases, impact the application database more broadly.

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.
