CVE-2020-37223: IObit Uninstaller 9.5.0.15 Unquoted Service Path Privilege Escalation

IObit Uninstaller 9.5.0.15 contains an unquoted service path vulnerability in the IObitUnSvr service that allows local attackers to escalate privileges to SYSTEM level. Attackers can place a malicious executable named IObit.exe in the C:\Program Files (x86)\IObit directory and restart the service to execute code with SYSTEM privileges.

Security readout for executives and security teams

Plain-English summary

This flaw can let someone who already has local access to a Windows machine turn limited access into SYSTEM-level control if IObit Uninstaller 9.5.0.15 is installed. The main business risk is endpoint takeover after an initial foothold, not remote internet compromise.

Executive priority

Prioritize remediation on managed Windows endpoints where IObit Uninstaller is present, especially shared workstations or systems with sensitive access. This is not described as remote unauthenticated compromise, but it can turn a limited local foothold into SYSTEM control.

Technical view

CVE-2020-37223 is a CWE-428 unquoted service path issue in the IObitUnSvr service for IObit Uninstaller 9.5.0.15. The CVSS 4.0 score is 8.5, with local attack vector, low complexity, low privileges required, no user interaction, and high impact to confidentiality, integrity, and availability.

Likely exposure

Exposure appears limited to Windows endpoints running IObit Uninstaller 9.5.0.15. The source bundle does not identify other affected versions or products. Risk is highest where users or attackers can gain local low-privileged access and interact with the affected service environment.

Exploitation context

The CVE is not listed as KEV in the supplied bundle. A public ExploitDB reference is cited, so public exploit information exists. The supplied sources do not prove active exploitation in the wild, and this should not be reported as actively exploited without stronger evidence.

Researcher notes

Do not broaden scope beyond IObit Uninstaller 9.5.0.15 based on the supplied evidence. No vendor patch version is named in the bundle. Treat ExploitDB as evidence of public exploit detail, not evidence of observed exploitation.

Mitigation direction

  • Inventory endpoints for IObit Uninstaller 9.5.0.15.
  • Remove affected installations if the software is not business-required.
  • Check IObit guidance for a corrected or supported version.
  • Restrict local software installation and write permissions on managed endpoints.
  • Monitor endpoint alerts for suspicious service changes or privilege escalation behavior.

Validation and detection

  • Identify hosts with IObit Uninstaller 9.5.0.15 installed.
  • Review the IObitUnSvr service configuration for an unquoted service path.
  • Check install directory permissions for unintended write access by standard users.
  • Review EDR logs for suspicious service restarts or unexpected binaries near the install path.
  • Confirm remediation by rechecking version and service path configuration.
