Affected:Netwrix

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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.

    Field note · TruePositive EditorialCurated

    Netwrix Auditor Insecure Object Deserialization Vulnerability — 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. Listed in the CISA KEV catalog (added 2023-07-11) — confirmed exploited in the wild, not theoretical. It is linked to known ransomware campaigns. FIRST EPSS puts the chance of exploitation in the next 30 days at ~36%. Treat it as real and prioritize remediation over triage.

    Remediation · TruePositive EditorialCurated

    Required action for Netwrix Auditor: Apply updates per vendor instructions or discontinue use of the product if updates are unavailable. CISA set a federal remediation due date of 2023-08-01. After patching, verify the vulnerable path is no longer reachable before closing the finding.
