Sangoma FreePBX Improper Authentication Vulnerability
CVE-2019-19006 is an improper authentication / authentication bypass vulnerability in Sangoma FreePBX affecting versions 15.0.16.26 and below, 14.0.13.11 and below, and 13.0.197.13 and below. Available reporting indicates the login flow sets a session for a supplied username before password validation fully completes, and does not properly sanitize the password parameter. By supplying the password parameter as an array element rather than a normal scalar value, an attacker can trigger failure in the authentication function before the session is unset, allowing retention of an authenticated session for an arbitrary chosen user, including the FreePBX administrator. Successful exploitation allows unauthorized access to services exposed through the FreePBX administrative interface.
