Description

This security bulletin contains information about 1 security vulnerability.

1) SQL injection (CVE-ID: CVE-2014-3857)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the (1) x_16 or (2) x_17 parameter to print.php within the Kerio Control Statistics feature.
