Description

This security bulletin contains information about 2 secuirty vulnerabilities.


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.


2) Missing Encryption of Sensitive Data (CVE-ID: CVE-2021-23222)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way the libpq process in PostgreSQL handles encrypted connections. A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. The attacker can exfiltrate the client's password or other confidential data that might be transmitted early in a session.
