Description

Invision Community up to and including version 5.0.6 contains a remote code
execution vulnerability in the theme editor's customCss endpoint. By crafting
a specially formatted `content` parameter with a `{expression="…"}`
construct, arbitrary PHP can be evaluated. This module leverages that flaw
to execute payloads or system commands as the webserver user.
