TorrentFlux action Script Insertion
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 administrator?s 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.
