"The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
CESA-2023:0113 advisory.
- A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects
in at least one schema, the ability to lure or wait for an administrator to create or update an affected
extension in that schema, and the ability to lure or wait for a victim to use the object targeted in
CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to
run arbitrary code as the victim role, which may be a superuser. (CVE-2022-2625)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
