Description

This security bulletin contains information about 1 vulnerability.


1) Man-in-the-middle attack (CVE-ID: CVE-2017-10789)

CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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.
