CISA's required action

What the flaw is

Netwrix Auditor User Activity Video Recording component contains an insecure objection deserialization vulnerability that allows an unauthenticated, remote attacker to execute code as the NT AUTHORITY\SYSTEM user. Successful exploitation requires that the attacker is able to reach port 9004/TCP, which is commonly blocked by standard enterprise firewalling.

CISA's description

Remote code execution vulnerabilities exist in the Netwrix Auditor User Activity Video Recording component affecting both the Netwrix Auditor server and agents installed on monitored systems. The remote code execution vulnerabilities exist within the underlying protocol used by the component, and potentially allow an unauthenticated remote attacker to execute arbitrary code as the NT AUTHORITY\SYSTEM user on affected systems, including on systems Netwrix Auditor monitors.
