Microsoft Windows Secondary Logon Service Privilege Escalation Vulnerability — A privilege escalation vulnerability exists in Microsoft Windows if the Windows Secondary Logon Service fails to properly manage request handles in memory. An attacker who successfully exploited this vulnerability could run arbitrary code as an administrator. Listed in the CISA KEV catalog (added 2022-03-03) — confirmed exploited in the wild, not theoretical. It is linked to known ransomware campaigns. FIRST EPSS puts the chance of exploitation in the next 30 days at ~37%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Microsoft Windows: Apply updates per vendor instructions. CISA set a federal remediation due date of 2022-03-24. After patching, verify the vulnerable path is no longer reachable before closing the finding.
