Altiris WMI Provider Allows Local Users to Read SYSTEM Files
CVE-2026-15379 Published on July 17, 2026

Arbitrary File Read as SYSTEM in Symantec ITMS
The Altiris WMI provider exposes a class (AltirisAgent_Stream) that allows any local standard user to read the contents of any file accessible to the SYSTEM account, bypassing filesystem ACLs. No admin privileges required. The provider reverts to the LocalSystem context when servicing WMI queries without re-impersonating the caller. Any local standard user can therefore read SYSTEM-readable files including configuration files, service logs, and secrets stored with SYSTEM/Administrator-only ACLs by querying the provider directly.
