What this means

Illumio Core Ven for Windows versions before 23.2.22-S1, 23.2.23-S1, 23.2.24-S1, 23.2.30-S1, 23.2.31-S1, 24.2.10-S1, 24.2.11-S1, 24.2.20-S1, 24.2.30-S1, 24.2.35-S1, 24.2.40-S1, 25.2.10-S1, 25.2.20-S1, 25.2.31-S1, 25.2.40-S1, 25.2.41-S1, and 26.2.12-S1 have incorrect permission assignment, allowing local privilege escalation to SYSTEM with code execution as NT AUTHORITY LOCAL SERVICE. An attacker can modify the VEN configuration to execute an injected command in the context of the SYSTEM account. The flaw exists within the VEN installer.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher 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.
