Description
This security bulletin contains information about 1 security vulnerability.
1) 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.
