"The version of postgresql installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-10978 advisory.

  - Incorrect privilege assignment in PostgreSQL allows a less-privileged application user to view or change
    different rows from those intended. An attack requires the application to use SET ROLE, SET SESSION
    AUTHORIZATION, or an equivalent feature. The problem arises when an application query uses parameters from
    the attacker or conveys query results to the attacker. If that query reacts to current_setting('role') or
    the current user ID, it May modify or return data as though the session had not used SET ROLE or SET
    SESSION AUTHORIZATION. The attacker does not control which incorrect user ID applies. Query text from
    less-privileged sources is not a concern here, because SET ROLE and SET SESSION AUTHORIZATION are not
    sandboxes for unvetted queries. Versions before PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21 are
    affected. (CVE-2024-10978)

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