### Official description

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.

Exploitation results in the placement of attacker-controlled PHP files in a web-accessible directory, executed as the www-data user.
