Amazon Linux 2 : 389-ds-base, --advisory ALAS2-2025-3025 (ALAS-2025-3025)

critical Nessus Plugin ID 269246

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of 389-ds-base installed on the remote host is prior to 1.3.10.2-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-3025 advisory.

A privilege escalation flaw from host to domain administrator was found in FreeIPA. This vulnerability is similar to CVE-2025-4404, where it fails to validate the uniqueness of the krbCanonicalName. While the previously released version added validations for the admin@REALM credential, FreeIPA still does not validate the root@REALM canonical name, which can also be used as the realm administrator's name. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration. (CVE-2025-7493)

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

Run 'yum update 389-ds-base' or or 'yum update --advisory ALAS2-2025-3025' to update your system.
