Detailsinfo

A vulnerability classified as critical has been found in Red Hat Enterprise Linux 6/7/8/9/10. This affects an unknown code of the component FreeIPA. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. CWE is classifying the issue as CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at access.redhat.com. This vulnerability is uniquely identified as CVE-2025-7493 since 07/11/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 11/26/2025).
