CVE-2021-23214: SQL Injection

Published Nov 12, 2021
·
Updated

PostgreSQL is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements when the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, which could allow the attacker to view, add, modify or delete information in the back-end database.

Other sources

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.
