Security readout for executives and security teams
Plain-English summary
Rockstar Games Launcher 1.0.37.349 has weak permissions on its service executable. A user who already has authenticated access to an affected machine could replace that executable and gain administrator-level control. This is most urgent for shared, unmanaged, or developer workstations where the launcher is installed.
Executive priority
Treat as a high-priority endpoint hygiene issue, not an internet-wide emergency. Prioritize corporate workstations where users have local access and the launcher is installed. Remove or update affected installations quickly, especially on shared or privileged-user machines.
Technical view
CVE-2021-47852 is a CWE-276 insecure file permissions issue in RockstarService.exe for Rockstar Games Launcher 1.0.37.349. The bundle describes authenticated privilege escalation by modifying the service executable. CVSS is 8.8 High. The provided vector says network attack, but the described weakness centers on local authenticated access to the affected executable.
Likely exposure
Exposure is limited to systems with Rockstar Games Launcher 1.0.37.349 installed. This is more likely on user workstations than servers. Organizations that allow personal software or gaming launchers on corporate endpoints should prioritize inventory and removal or update decisions.
Exploitation context
A public ExploitDB entry is cited, so proof-of-concept information is publicly available. The source bundle does not show CISA KEV listing or confirmed active exploitation. Abuse requires authenticated access to an affected system and the ability to modify the weakly protected service executable.
Researcher notes
The advisory data identifies a specific affected version and weak service executable permissions. Evidence for a fixed version is not included in the source bundle. The CVSS vector and textual description appear somewhat inconsistent on attack vector, so validate conditions against the original advisory before scoring internally.
Mitigation direction
- Inventory endpoints for Rockstar Games Launcher 1.0.37.349.
- Check Rockstar guidance and launcher update channels for remediation details.
- Update or remove the launcher where business need is absent.
- Restrict non-business software installation on managed endpoints.
- Review service executable permissions and correct weak ACLs using approved guidance.
Validation and detection
- Confirm whether Rockstar Games Launcher 1.0.37.349 is installed.
- Verify the presence and permissions of RockstarService.exe.
- Review endpoint management logs for unauthorized launcher installations.
- Check whether current vendor guidance identifies a fixed launcher version.
- Monitor affected systems for unexpected administrator account changes.

Incorrect Default Permissions
Incorrect Default Permissions represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
