"The version of postgresql installed on the remote host is prior to 9.2.24-8. It is, therefore, affected by a
vulnerability as referenced in the ALAS2-2025-3035 advisory.

    Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to
    inject arbitrary code for restore-time execution as the client operating system account running psql to
    restore the dump, via psql meta-commands.  pg_dumpall is also affected.  pg_restore is affected when used
    to generate a plain-format dump.  This is similar to MySQL CVE-2024-21096.  Versions before PostgreSQL
    17.6, 16.10, 15.14, 14.19, and 13.22 are affected. (CVE-2025-8714)

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.");
