PostgreSQL 15.x < 15.4 Protection Mechanism Failure

medium Nessus Plugin ID 179921

Language:

Synopsis

The remote database server is affected by a protection mechanism failure vulnerability

Description

The version of PostgreSQL installed on the remote host is 15 prior to 15.4. As such, it is potentially affected by a vulnerability :

 - PostgreSQL 15 introduced the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some row that INSERT policies do not forbid, a user could store such rows. Subsequent consequences are application-dependent. This affects only databases that have used CREATE POLICY to define a row security policy.

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

Solution

Upgrade to PostgreSQL 15.4 or later
