Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way PostgreSQL handles encrypted connections. When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.


Remediation

Install updates from vendor's website.
