Amazon Linux 2 : postgresql (ALASPOSTGRESQL11-2023-004)

high Nessus Plugin ID 181957

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of postgresql installed on the remote host is prior to 11.20-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2POSTGRESQL11-2023-004 advisory.

 - IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ). If an administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with database-level CREATE privilege can execute arbitrary code as the bootstrap superuser. (CVE-2023-39417)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update postgresql' to update your system.
