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.

Netwrix Auditor before 9.8 has insecure permissions on %PROGRAMDATA%\Netwrix Auditor\Logs\ActiveDirectory\ and sub-folders. In addition, the service Netwrix.ADA.StorageAuditService (which writes to that directory) does not perform proper impersonation, and thus the target file will have the same permissions as the invoking process (in this case, granting Authenticated Users full access over the target file). This vulnerability can be triggered by a low-privileged user to perform DLL Hijacking/Binary Planting attacks and ultimately execute code as NT AUTHORITY\SYSTEM with the help of Symbolic Links.
