Security readout for executives and security teams
Plain-English summary
This flaw lets an unauthenticated remote attacker potentially run code as SYSTEM through Netwrix Auditor’s User Activity Video Recording component. Because both the Auditor server and monitored agents may be affected, compromise could extend into systems being monitored. CISA KEV inclusion means exploitation has been observed.
Executive priority
Handle as urgent. This is a critical, known-exploited vulnerability that can lead to SYSTEM-level compromise on security monitoring infrastructure and monitored endpoints.
Technical view
CVE-2022-31199 is a critical network RCE in the underlying protocol of Netwrix Auditor User Activity Video Recording. The source bundle maps it to CWE-502 and CVSS 9.8. Successful exploitation may execute arbitrary code as NT AUTHORITY\SYSTEM on affected Auditor servers or agents.
Likely exposure
Exposure is most likely where Netwrix Auditor uses the User Activity Video Recording component, especially if server or agent communication surfaces are reachable from untrusted networks. The bundle does not provide exact affected versions or CPEs.
Exploitation context
CISA KEV status supports known exploitation. The provided bundle does not include exploit volume, affected campaigns, proof-of-concept details, or currently used attacker tooling.
Researcher notes
Evidence is strong for severity, component, privilege impact, and KEV status. Evidence is incomplete in the bundle for exact affected versions, fixed versions, exploit details, and vendor-specific mitigations.
Mitigation direction
- Inventory Netwrix Auditor servers and monitored systems running its agents.
- Check Netwrix and Bishop Fox guidance for affected versions and fixed builds.
- Apply vendor-approved updates or configuration changes as directed.
- Restrict access to Auditor server and agent communication paths during remediation.
- Treat internet-exposed or broadly reachable instances as highest priority.
Validation and detection
- Confirm whether User Activity Video Recording is enabled in each deployment.
- Verify installed Netwrix Auditor server and agent versions against vendor guidance.
- Review logs for unusual service activity around Auditor servers and monitored agents.
- Check network exposure for relevant server and agent communication surfaces.
- Document remediation status for KEV-driven risk tracking.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
