Security readout for executives and security teams
Plain-English summary
Remote Mouse for Windows has a local privilege escalation flaw in versions 3.008 and 4.002. A user who already has local access could abuse the service configuration to run code with elevated privileges. This is mainly a risk on shared workstations, lightly managed endpoints, or systems where Remote Mouse is installed unnecessarily.
Executive priority
Treat as a high-priority endpoint hygiene issue, not a broad internet emergency. Prioritize removal or remediation on shared, privileged, or poorly monitored Windows systems. Ask IT to confirm whether Remote Mouse is approved software and whether affected versions exist in the environment.
Technical view
CVE-2021-47792 is a CWE-428 unquoted service path issue in RemoteMouseService. The CVSS v4 vector is local, low complexity, low privileges, and no user interaction, with high confidentiality, integrity, and availability impact. Public sources list affected Remote Mouse versions 3.008 and 4.002. Exploit-DB has a public exploit reference, but CISA KEV is not indicated.
Likely exposure
Exposure is limited to endpoints where affected Remote Mouse versions are installed. Because exploitation requires local access, internet exposure is not the primary concern. Risk increases where standard users can log in, where endpoint controls are weak, or where the product is installed outside normal software governance.
Exploitation context
Public exploit information exists via Exploit-DB, but the provided sources do not show confirmed active exploitation or KEV listing. An attacker needs local access and low privileges, then abuses the Windows service path weakness to elevate privileges. This is typically a post-compromise or insider-risk escalation issue.
Researcher notes
The source bundle identifies Remote Mouse 3.008 and 4.002, with the titled advisory focusing on 4.002. The record’s publication date is 2026 despite the 2021 CVE namespace. No vendor patch version is provided in the supplied evidence, so remediation should be verified against vendor guidance or direct service configuration review.
Mitigation direction
- Inventory Windows endpoints for Remote Mouse versions 3.008 and 4.002.
- Remove Remote Mouse where it is not business-required.
- Check the vendor site and advisory sources for current fixed versions or guidance.
- If retained, correct the service path quoting through approved administrative change control.
- Restrict local user access and monitor endpoints running Remote Mouse.
Validation and detection
- Confirm whether Remote Mouse is installed and record the installed version.
- Inspect RemoteMouseService configuration for an unquoted executable path containing spaces.
- Verify whether the service runs with elevated privileges.
- Review endpoint telemetry for suspicious executable placement near service path directories.
- Recheck service configuration after upgrade, removal, or administrative remediation.

Unquoted Search Path or Element
Unquoted Search Path or Element represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
