Description
This security bulletin contains information about 1 security vulnerability.
1) Missing Encryption of Sensitive Data (CVE-ID: CVE-2021-23214)
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 update from vendor's website.
