high Nessus Plugin ID 170543

Language:

Synopsis

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

Description

The version of postgresql95 installed on the remote host is prior to 9.5.24-1.83. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1660 advisory.

 - 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. (CVE-2021-23214)

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 postgresql95' to update your system.
