Description
This security bulletin contains information about 1 vulnerability.
1) Missing Encryption of Sensitive Data (CVE-ID: CVE-2021-23214)
CWE-ID: CWE-311 - Missing Encryption of Sensitive Data
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
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.
