## Technical details

The Altiris WMI provider exposes a specific class, AltirisAgent_Stream, which fails to properly re-impersonate the calling user when servicing queries. Instead, the provider reverts to the LocalSystem security context. A local attacker with standard user privileges can exploit this by querying the WMI provider to read the contents of any file on the filesystem that is readable by the SYSTEM account, effectively bypassing NTFS Access Control Lists (ACLs). This can be used to extract sensitive configuration files, service logs, or secrets. The vulnerability affects Symantec IT Management Suite versions 8.8 and 8.8.1.
