Input passed to the action variable is not properly sanitized before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in an administrators browser session in context of an affected site when the Activity Log is viewed.

TorrentFlux action Script Insertion
TITLE:
TorrentFlux action Script Insertion
CRITICAL:
Not Critical
IMPACT:
Cross Site Scripting
WHERE:
>From remote
SOFTWARE:
TorrentFlux 2.x
DESCRIPTION:
I have discovered a vulnerability in TorrentFlux, which can be exploited by malicious users to conduct script insertion attacks.
Input passed to the action variable is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in an administrators browser session in context of an affected site when the Activity Log is viewed.
The vulnerability has been confirmed in version 2.1. Other versions may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
/admin.php
Line 336:
$output .=
.htmlentities($action, ENT_QUOTES).
;
Line 398:
echo .htmlentities($action, ENT_QUOTES).";
