Unsafe deserialization of untrusted JSON allows execution of arbitrary code on affected releases of the Illumio PCE. Authentication to the API is required to exploit this vulnerability. The flaw exists within the networktraffic API endpoint. An attacker can leverage this vulnerability to execute code in the context of the PCE’s operating system user.

The OpenSSL library bundled with the Illumio VEN for Windows is affected by an uncontrolled search path vulnerability. A low-privileged, authenticated local attacker could potentially leverage this vulnerability to execute arbitrary code with SYSTEM privileges.

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.
