Nagios: >> Nagios Xi >> 2009 Security Vulnerabilities
Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the handling of the "backend_url" JavaScript link. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

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.

Nagios XI < 2026R1 is vulnerable to an authenticated command injection vulnerability within the MongoDB Database, MySQL Query, MySQL Server, Postgres Server, and Postgres Query wizards. It is possible to inject shell characters into arguments provided to the service and execute arbitrary system commands on the underlying host as the `nagios` user.

Nagios XI < 2024R1.3.2 contains a remote code execution vulnerability by chaining two flaws: an arbitrary file upload and a path traversal in the Core Config Snapshots interface. The issue arises from insufficient validation of file paths and extensions during MIB upload and snapshot rename operations. Exploitation results in the placement of attacker-controlled PHP files in a web-accessible directory, executed as the www-data user.
