Description
This security bulletin contains information about 1 security vulnerability.
1) Man-in-the-middle attack (CVE-ID: CVE-2017-10789)
The vulnerability allows a remote attacker to conduct man-in-the-middle attack on the target system.
The vulnerability exists due to use of the mysql_ssl=1 setting to mean that SSL is optional (even though this setting's documentation has a "your communication with the server will be encrypted" statement). A remote attacker can conduct man-in-the-middle attack, intercept of the communication channel between the affected app and spoof servers via a cleartext-downgrade attack.
