Security readout for executives and security teams
Plain-English summary
CVE-2018-9042 is a local vulnerability in Advanced SystemCare Ultimate 11.0.1.58. A local user can trigger a Windows crash through the Monitor_win10_x64.sys driver. The public record also says other impact may be possible, but does not define it.
Executive priority
Treat this as a targeted endpoint stability risk, not an internet-scale emergency. Prioritize discovery and cleanup on shared Windows systems and systems where untrusted users can run local software.
Technical view
The issue is improper validation of input values handled by IOCTL 0x9c402000 in Monitor_win10_x64.sys. The documented impact is local denial of service through BSOD, with unspecified other impact only described as possible. No CVSS, CWE, vendor fix, or detailed affected CPE data is provided.
Likely exposure
Exposure is limited to Windows endpoints with Advanced SystemCare Ultimate 11.0.1.58 and the Monitor_win10_x64.sys driver installed. Risk is highest where local users or locally executing malware can interact with the driver.
Exploitation context
The CVE is not listed as KEV in the supplied bundle. A public GitHub reference is categorized as a BSOD proof of concept, but the sources do not establish active exploitation or reliable privilege escalation.
Researcher notes
The source data is sparse: no CVSS vector, CWE, patch reference, or affected CPEs are supplied. Keep analysis constrained to local denial of service unless additional vendor or researcher evidence supports broader impact.
Mitigation direction
- Inventory endpoints for Advanced SystemCare Ultimate 11.0.1.58.
- Check vendor guidance for patched versions or removal recommendations.
- Remove the product where it is not business-required.
- Prioritize controls on shared or multi-user Windows systems.
- Monitor affected endpoints for unexpected BSOD events.
Validation and detection
- Confirm whether Monitor_win10_x64.sys is present on Windows endpoints.
- Verify installed Advanced SystemCare Ultimate version data.
- Review crash telemetry for driver-related BSOD patterns.
- Check asset inventory for shared-user or kiosk exposure.
- Track vendor advisories before claiming remediation status.
