Yogurt Social Network is a social network php/Mysql script
module for multiple CMS Systems like Xoops,e-xoops,bcoos and
impressCMS and probably in all CMS based in Xoops code.

Yogurt Social Network contains a flaw that allows a remote
cross site scripting attack.This flaw exists because
the application does not validate 'uid' variable upon
submission to Multiple scripts script in yogurt module.
This could allow a user to create a specially crafted URL
that would execute arbitrary code in a user's browser within
the trust relationship between the browser and the server,
leading loss ofintegrity.
