Subject: EJ3 TOPo - Cross Site Scripting Vulnerability


- Advisory: EJ3 TOPo Cross Site Scripting Vulnerability
- Author: Yunus Emre Yilmaz || Yns [mail@...usemreyilmaz.com]

- Application: EJ3 TOPo ( http://ej3soft.ej3.net )
- Affected Version : v2.2.178 ( maybe older versions..)
- Risk : Critical

– Details : If an attacker access /code/inc_header.php directly , he can bypass $gTopNomBer variable.(Register_globals must be “on”)

Problem is about not defining or filtering the variable.

– Proof Of Concept : access /code/inc_header.php like
inc_header.php?gTopNombre=“><script>alert(document.cookie)</script>

and print user’s cookie.So an attacker can escape admin’s cookie.

– Release Date: 2006/02/28
– Contacted to vendor : 2006/02/28
