Local Privilege Escalation via Unquoted Service Path in OCS Inventory NG 2.3.0.0

IdentifiersCVE-2023-53947CWE-428· Unquoted Search Path or Element

OCS Inventory NG 2.3.0.0 contains an unquoted Windows service path vulnerability (CWE-428). If the service executable path includes spaces and is not wrapped in quotes, Windows may search for and execute an attacker-controlled executable placed earlier in the interpreted search order (e.g., in a writable directory along the path). A local attacker can plant a malicious executable in the unquoted service path and, upon service restart, have it executed in the service’s security context, resulting in SYSTEM-level code execution.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a local attacker to escalate privileges to NT AUTHORITY\SYSTEM by achieving execution in the affected service context when the service is started/restarted. This can enable full host compromise (e.g., disabling security controls, credential theft, persistence) commensurate with SYSTEM privileges.

Mitigation

If you can’t patch tonight, do this now.

Restrict write permissions on directories in the service executable path (and common parent directories), monitor for creation of suspicious executables in those locations, and alert on unexpected service restarts and anomalous child processes spawned by the service. Where feasible, run services with least privilege rather than LocalSystem to reduce impact.

Remediation

Patch, then assume compromise.

Quote the affected Windows service ImagePath (wrap the full executable path in double quotes) and/or apply the vendor-provided fix/patch for OCS Inventory NG addressing CVE-2023-53947. After correcting the service configuration, restart the service to ensure the updated path is in effect and validate no unintended executables exist along the service path.
