CVE-2020-25694 (GCVE-0-2020-25694)

Vulnerability from cvelistv5 – Published: 2020-11-16 00:38 – Updated: 2024-08-04 15:40

Summary

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Severity

No CVSS data available.
