TencentOS Server 4: freeipa (TSSA-2025:0827)

high Nessus Plugin ID 272248

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0827 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2025-7493:
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.

Tenable has extracted the preceding description block directly from the Tencent Linux 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

Update the affected packages.
