Security readout for executives and security teams
Plain-English summary
TotalAV 5.15.69 has a Windows service configuration flaw that can let a local, low-privileged attacker gain SYSTEM-level control. This matters most on shared workstations, kiosks, or endpoints where attackers may already have limited access.
Executive priority
Prioritize remediation on shared or high-value Windows endpoints. This is not a remote internet exploit based on available evidence, but successful exploitation could give an attacker full local system control.
Technical view
CVE-2021-47787 is a CWE-428 unquoted service path issue in multiple TotalAV 5.15.69 services running as LocalSystem. The CVSS v4 score is 8.5, with local attack vector, low complexity, low privileges required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to systems running TotalAV version 5.15.69. The vulnerability requires local access, so internet-facing exposure is not indicated by the provided sources.
Exploitation context
The source bundle references an ExploitDB entry, indicating public exploit information exists. The CVE is not listed as KEV, and the provided sources do not state active exploitation in the wild.
Researcher notes
Evidence names TotalAV 5.15.69 only. No vendor patch version or formal workaround is included in the provided sources. Treat ExploitDB as proof of public exploit detail, not proof of active exploitation.
Mitigation direction
- Identify endpoints running TotalAV 5.15.69.
- Check TotalAV vendor guidance for patched or recommended versions.
- Upgrade, remove, or replace the affected version if vendor guidance supports it.
- Review and correct unquoted LocalSystem service paths where approved.
- Restrict local write access to service path directories.
Validation and detection
- Inventory TotalAV installations and confirm exact version.
- Review TotalAV Windows services for unquoted executable paths.
- Confirm affected services run with LocalSystem privileges.
- Verify local users cannot write to relevant service path directories.
- Document remediation status per endpoint.
