Description

Nagios XI versions prior to 2024R1.2 are vulnerable to remote code execution (RCE) through its NRDP (Nagios Remote Data Processor) server plugins. Insufficient validation of inbound NRDP request parameters allows crafted input to reach command execution paths, enabling attackers to execute arbitrary commands on the underlying host in the context of the web/Nagios service.
