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.
Affected Products

Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2022-31199 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
