Security readout for executives and security teams
Plain-English summary
This CVE is a local privilege escalation in Ivanti WorkSpace Control. A low-privileged authenticated user may gain administrator rights because pwrgrid.exe checks user-controlled HKCU registry locations before launching an application with elevated rights. It matters most on shared or managed Windows endpoints.
Executive priority
Treat this as a focused endpoint hardening and patching issue. It is not described as remotely exploitable, but it can turn a low-privilege foothold into administrator control on affected managed systems.
Technical view
Ivanti WorkSpace Control before 10.4.40.0 is affected. The issue involves pwrgrid.exe prioritizing Current User registry hives when starting elevated applications, allowing registry hijacking by a locally authenticated low-privilege user. The source bundle provides no CVSS, CWE, or detailed vendor mitigation text.
Likely exposure
Exposure is limited to systems running Ivanti WorkSpace Control versions before 10.4.40.0 where untrusted or lower-privileged users can log on locally.
Exploitation context
No active exploitation is supported by the provided sources, and the CVE is not listed as KEV. Exploitation requires local authenticated access, so this is mainly a post-access privilege escalation risk rather than an internet-facing entry point.
Researcher notes
The public data is sparse: no CVSS, CWE, exploit status, or detailed remediation content is included in the bundle. The key technical signal is HKCU registry precedence in pwrgrid.exe during elevated application launch.
Mitigation direction
- Inventory Ivanti WorkSpace Control deployments and record exact versions.
- Prioritize vendor-supported remediation for versions before 10.4.40.0.
- Review Ivanti guidance before applying compensating controls.
- Limit local interactive access on affected systems where possible.
- Monitor for suspicious privilege escalation behavior on managed endpoints.
Validation and detection
- Confirm whether Ivanti WorkSpace Control is installed on Windows endpoints.
- Verify the installed version is 10.4.40.0 or later.
- Check whether low-privileged users can log on locally to affected systems.
- Review endpoint logs for unusual elevated application launches.
- Document any systems requiring vendor remediation or exception handling.
