Summary
Several services are accessing named pipes in Ivanti Endpoint Manager through 2020.1.1 with default or overly permissive security attributes; as these services run as user ‘NT AUTHORITY\SYSTEM’, the issue can be used to escalate privileges from a local standard or service account having SeImpersonatePrivilege (eg. user ‘NT AUTHORITY\NETWORK SERVICE’).
Exploit prediction
0.47% chance of exploitation in the next 30 days, higher than 40% of all scored CVEs (FIRST EPSS, 2026-11-08).
