What is CVE-2026-15379?
CVE-2026-15379 is a medium-severity vulnerability in Broadcom Symantec IT Management Suite, published on 17 Jul 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
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.
