Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Incorrect permission assignment allows local privilege escalation to SYSTEM on affected releases of the Illumio VEN for Windows. Code execution as NT AUTHORITY\LOCAL SERVICE on the Windows host is required to exploit this vulnerability. The flaw exists within the VEN installer, which grants LOCAL SERVICE full access to the VEN data and installation folders, whose configuration and state files are read and trusted by the SYSTEM-privileged illumio-ven-ctl component. An attacker can leverage this vulnerability to modify the VEN configuration so that illumio-ven-ctl executes an injected command in the context of the SYSTEM account.
