CVE-2025-34284
Nagios XI versions prior to 2024R2 contain a command injection vulnerability in the WinRM plugin.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Nagios XI versions prior to 2024R2 contain a command injection vulnerability in the WinRM plugin. Insufficient validation of user-supplied parameters allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to modify configuration, exfiltrate data, disrupt monitoring operations, or execute commands on the underlying host operating system.
