In Advanced SystemCare Ultimate 11.0.1.58, the driver file (Monitor_x86.sys) allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of not validating input values from IOCtl 0x9c402004.

Security readout for executives and security teams

Plain-English summary

CVE-2018-9000 is a local denial-of-service issue in Advanced SystemCare Ultimate 11.0.1.58. A vulnerable Windows driver can mishandle input and crash the system with a BSOD. The public record also says unspecified other impact may be possible, but the provided sources do not prove broader compromise.

Executive priority

Treat this as a focused endpoint stability risk, not a confirmed remote breach risk. Prioritize remediation where affected systems support business-critical workstations, shared kiosks, or environments where local users are untrusted.

Technical view

The CVE describes insufficient input validation in Monitor_x86.sys, reachable through a specific IOCTL path. A local user can trigger a Windows crash. No CVSS score, CWE, vendor advisory, patch version, or confirmed privilege escalation details are included in the supplied sources.

Likely exposure

Exposure appears limited to endpoints running Advanced SystemCare Ultimate 11.0.1.58 with the vulnerable Monitor_x86.sys driver present. The source bundle does not identify other affected versions, platforms, or CPEs.

Exploitation context

The record references public proof-of-concept material for BSOD behavior. CISA KEV status is false in the bundle, and no cited source states active exploitation in the wild.

Researcher notes

Evidence is sparse. The CVE confirms local BSOD impact and possible unspecified other impact, but lacks CVSS, CWE, CPEs, vendor fix details, and exploitation-in-the-wild evidence. Avoid assuming privilege escalation without additional primary evidence.

Mitigation direction

  • Identify systems with Advanced SystemCare Ultimate 11.0.1.58 installed.
  • Check vendor guidance for fixed versions or removal instructions.
  • Remove or disable the vulnerable driver where operationally safe.
  • Restrict local interactive access on affected endpoints.
  • Monitor endpoint crashes involving Monitor_x86.sys.

Validation and detection

  • Inventory installed Advanced SystemCare Ultimate versions.
  • Check whether Monitor_x86.sys exists on endpoints.
  • Review crash dumps for Monitor_x86.sys involvement.
  • Confirm any vendor-provided update replaces the vulnerable driver.
  • Document affected assets and remediation status.
