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 vulnerability in Broadcom Symantec IT Management Suite (CVE-2026-15379) involves the AltirisAgent_Stream class exposed by the Altiris WMI provider. When servicing WMI queries, the provider reverts to the LocalSystem context and does not re-impersonate the calling user. This allows any local standard user to read any file accessible to the SYSTEM account, effectively bypassing filesystem access control lists (ACLs). No administrative privileges are required to exploit this issue. The affected versions are 8.8 and 8.8.1. The CVSS 4.0 base score is 5.1, indicating a medium severity vulnerability.
Potential Impact
An attacker with local standard user access can read sensitive files that are normally restricted to the SYSTEM or Administrator accounts. This includes configuration files, service logs, and secrets protected by filesystem ACLs. The unauthorized disclosure of such information could facilitate further attacks or compromise system confidentiality. There is no indication of privilege escalation or remote exploitation in the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict local user access to trusted personnel only and monitor for unusual local activity. Avoid running untrusted code or scripts on affected systems.
