TorrentFlux user_id Script Insertion
TITLE:
TorrentFlux ?user_id? 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.
Data passed to the ?users? array 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.
