CVE-2020-37229: OKI sPSV Port Manager 1.0.41 Unquoted Service Path Privilege Escalation

OKI sPSV Port Manager 1.0.41 contains an unquoted service path vulnerability in the sPSVOpLclSrv service that allows local attackers to escalate privileges by inserting executable files into the unquoted path. Attackers can place a malicious executable in a directory within the service path that will execute with LocalSystem privileges when the service restarts or the system reboots.

Security readout for executives and security teams

Plain-English summary

OKI sPSV Port Manager 1.0.41 has a Windows service configuration flaw. A user who already has local access may be able to gain full system privileges when the service restarts or the computer reboots. This is a local privilege escalation issue, not a remote internet-facing vulnerability.

Executive priority

Treat as high priority where the software is installed on multi-user or sensitive systems. It can turn limited local access into full system control, but it does not appear to be remotely exploitable from the provided sources.

Technical view

The sPSVOpLclSrv service uses an unquoted service path. Under Windows service path parsing behavior, a low-privileged local attacker may place an executable in a reachable path location and have it run as LocalSystem during service restart or reboot. The issue is classified as CWE-428 and affects OKI sPSV Port Manager 1.0.41.

Likely exposure

Exposure is limited to Windows systems with OKI sPSV Port Manager version 1.0.41 installed and the affected sPSVOpLclSrv service present. Risk increases on shared workstations, print-management hosts, or endpoints where non-admin users can write to directories in the service path.

Exploitation context

A public Exploit-DB entry exists, so defenders should assume exploit knowledge is available. The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires local access and depends on service restart or system reboot behavior.

Researcher notes

Evidence comes from CVE data, VulnCheck, and Exploit-DB. No official OKI security advisory or fixed version is included in the provided sources. Avoid overstating active exploitation; only public exploit availability is supported here.

Mitigation direction

  • Check OKI guidance for updated software or supported remediation.
  • Upgrade, remove, or disable the affected component if not required.
  • Correct the unquoted service path using vendor-approved change procedures.
  • Restrict write permissions on directories in the service path.
  • Prioritize shared endpoints and print-management systems.

Validation and detection

  • Inventory systems for OKI sPSV Port Manager 1.0.41.
  • Confirm whether service sPSVOpLclSrv exists.
  • Review the service ImagePath for unquoted spaces.
  • Check write permissions along the service path directories.
  • Verify remediation by rechecking service path quoting and permissions.
