Security readout for executives and security teams
Plain-English summary
CVE-2022-31877 is a high-severity privilege-escalation issue in MSI Center v1.0.41.0. A low-privileged attacker could use a crafted TCP packet against MSI.TerminalServer.exe to gain elevated control. This matters most on workstations where MSI Center is installed and the vulnerable component is running.
Executive priority
Treat as a high-priority endpoint hygiene issue where MSI Center is deployed. It is not currently supported as actively exploited by the provided sources, but successful abuse could give an attacker elevated privileges on affected machines.
Technical view
The CVE describes improper verification of data authenticity, CWE-345, in MSI.TerminalServer.exe within MSI Center v1.0.41.0. CVSS 3.1 is 8.8 with network attack vector, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Likely exposure is limited to systems running MSI Center v1.0.41.0, especially MSI endpoints or systems with MSI utilities installed. The CVE metadata does not provide normalized CPEs or broader affected-version ranges, so asset validation is required.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The issue requires low privileges but no user interaction, and targets a TCP-handling component, making it relevant for internal endpoint compromise scenarios.
Researcher notes
The CVE record identifies MSI Center v1.0.41.0 and MSI.TerminalServer.exe, but affected metadata lacks CPEs and broader version detail. The referenced researcher write-up should guide deeper review, while avoiding assumptions about unlisted versions or fixes.
Mitigation direction
- Identify systems running MSI Center v1.0.41.0.
- Check MSI or software-vendor guidance for fixed versions or official remediation.
- Remove or disable MSI Center where it is not business-required.
- Limit network reachability to MSI.TerminalServer.exe using approved endpoint controls.
- Prioritize remediation on shared, high-value, or administrator-used workstations.
Validation and detection
- Confirm MSI Center version on MSI-managed endpoints.
- Check whether MSI.TerminalServer.exe is present and running.
- Review endpoint controls for unnecessary TCP exposure to the component.
- Verify any vendor-recommended update or removal was completed.
- Monitor for unusual activity involving MSI.TerminalServer.exe.

Insufficient Verification of Data Authenticity
Insufficient Verification of Data Authenticity represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
