Technical description

An issue was discovered in Opsview Monitor Agent 6.8. An unauthenticated remote attacker can call check_nrpe against affected targets, specifying known NRPE plugins, which in default installations are configured to accept command control characters and pass them to command-line interpreters for NRPE plugin execution. This allows the attacker to escape NRPE plugin execution and execute commands remotely on the target as NT_AUTHORITY\SYSTEM.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
