CVE-2022-50808: CoolerMaster MasterPlus 1.8.5 - 'MPService' Unquoted Service Path

CoolerMaster MasterPlus 1.8.5 contains an unquoted service path vulnerability in the MPService that allows local attackers to execute code with elevated system privileges. Attackers can drop a malicious executable in the service path and trigger code execution during service startup or system reboot.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50808 is a local privilege escalation flaw in Cooler Master MasterPlus 1.8.5. A user already on a Windows system could abuse the MPService service configuration to run code with elevated privileges. This is most urgent for endpoints where MasterPlus is installed and untrusted or compromised local users may exist.

Executive priority

Treat as a high-priority endpoint hardening issue, not an internet-facing emergency. Prioritize systems where MasterPlus is installed on managed corporate devices, especially where users lack administrative rights and privilege escalation would materially increase breach impact.

Technical view

MasterPlus 1.8.5 MPService has an unquoted service path issue classified as CWE-427. The CVSS 4.0 score is 8.5, with local attack vector, low complexity, low privileges required, and high confidentiality, integrity, and availability impact. Sources describe execution during service startup or reboot if the vulnerable path condition is abused.

Likely exposure

Exposure is limited to systems running Cooler Master MasterPlus version 1.8.5 with the MPService installed. The issue requires local access or an existing foothold, so it is most relevant to endpoint hardening, post-compromise escalation, shared workstations, and gaming or peripheral-management PCs in enterprise environments.

Exploitation context

The CVE is not listed as CISA KEV in the provided data. A public Exploit-DB reference exists, so defenders should assume practical abuse details are publicly available. The provided sources do not claim active exploitation in the wild.

Researcher notes

The affected version is specifically listed as Cooler Master MasterPlus 1.8.5. Patch status is not established in the provided sources. Avoid assuming broader version impact without vendor confirmation. Public exploit reference increases validation urgency, but active exploitation is not evidenced here.

Mitigation direction

  • Identify endpoints with Cooler Master MasterPlus 1.8.5 installed.
  • Check Cooler Master guidance for an updated or corrected MasterPlus release.
  • Remove MasterPlus where it is not business-required.
  • Ensure MPService service paths are properly quoted where supported by vendor guidance.
  • Restrict write permissions on service path directories to trusted administrators only.

Validation and detection

  • Inventory installed MasterPlus versions on Windows endpoints.
  • Confirm whether MPService exists on each system.
  • Review MPService ImagePath for unquoted paths containing spaces.
  • Check directory ACLs along the service path for non-admin write access.
  • Re-scan after update, removal, or configuration correction.
