Nagios XI < 2024R1.3.2 RCE via WinRM Configuration Wizard
Nagios XI versions prior to 2024R1.3.2 contain a remote command execution vulnerability in the WinRM Configuration Wizard. Insufficient validation of user-supplied input 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.
Nagios addresses this vulnerability as "Nagios XI was vulnerable to remote command execution through the WinRM configuration wizard" and as a part of "Fixed RCE in WinRM Wizard."
