Vulnerability identifier: #VU58113
Vulnerability risk: Medium
CVSSv4.0: 4.9 [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]
CVE-ID:
CWE-ID:
CWE-311
Exploitation vector: Local network
Exploit availability: No
Vulnerable software:
PostgreSQL
Server applications /
Database software
Vendor: PostgreSQL Global Development Group
Description
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.
Mitigation
Install updates from vendor's website.
Vulnerable software versions
PostgreSQL: 9.6.0 - 9.6.23, 10.1 - 14.0
