Summary

CVE-2022-41033 is a high-severity Type Confusion (CWE-843) vulnerability in Microsoft Windows Server 2008. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 25% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2022-41033 is an elevation-of-privilege vulnerability in the Windows COM+ Event System Service, assigned CWE-843 and carrying a CVSS 3.1 base score of 7.8. The flaw permits a local attacker to obtain higher privileges on affected Windows systems without requiring user interaction.

An authenticated local user can exploit the weakness to achieve full control over confidentiality, integrity, and availability on the host. Because the attack vector is local and the required privileges are only low, any process or user already present on the system can leverage the bug to escalate to SYSTEM-level access.

Microsoft has published security updates and advisory guidance at the listed MSRC URLs to address the issue. The vulnerability also appears in CISA’s Known Exploited Vulnerabilities catalog, confirming observed in-the-wild exploitation, although the associated EPSS score has remained flat at 0.0174.
