CVE-2026-15379: Vulnerability in Broadcom Symantec IT Management Suite
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.
AI Analysis
Technical Summary
The AltirisAgent_Stream class in the Altiris WMI provider of Broadcom Symantec IT Management Suite (versions 8.8 and 8.8.1) improperly handles security context during WMI queries. It executes queries under the LocalSystem account without re-impersonating the calling user, allowing any local standard user to read any file accessible to SYSTEM. This bypasses filesystem access controls and exposes sensitive data without requiring elevated privileges.
Potential Impact
Local standard users can read files normally restricted to the SYSTEM account, including sensitive configuration files, service logs, and secrets protected by SYSTEM/Administrator ACLs. This unauthorized access could lead to information disclosure but does not allow privilege escalation or remote exploitation based on the available data.
Mitigation Recommendations
No official patch or remediation is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local user access on affected systems to trusted personnel only to minimize risk.
