Advanced Electron Forum v1.0.9 (AEF)
Exploit patched current version.
Remote File Inclusion / CSRF
In Admin control panel there is option to Import Skins and one choice is using a web URL.
"Specify the URL of the theme on the net. The theme file must be a compressed archive (zip, tgz, tbz2, tar)."
However there is no CSRF token or check made that this is a valid request made by the currently logged in user, resulting
in arbitrary remote file imports from an attacker if the user visits or clicks an malicious link. Victims will then be left
open to arbitrary malicious file downloads from anywhere on the net which may be used as a platform for further attacks...
