Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-547 advisory.Late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY in PostgreSQL allows an object creator to execute arbitrary SQL functions as the command issuer. The command intends to run SQL functions as the owner of the materialized view, enabling safe refresh of untrusted materialized views. The victim is a superuser or member of one of the attacker's roles. The attack requires luring the victim into running REFRESH MATERIALIZED VIEW CONCURRENTLY on the attacker's materialized view. As part of exploiting this vulnerability, the attacker creates functions that use CREATE RULE to convert the internally-built temporary table to a view. Versions before PostgreSQL 15.6, 14.11, 13.14, and 12.18 are affected. The only known exploit does not work in PostgreSQL 16 and later. For defense in depth, PostgreSQL 16.2 adds the protections that older branches are using to fix their vulnerability. (CVE-2024-0985)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
