CVE-2025-4404
CriticalCVSS 9.1Exploitation Probability (EPSS)
High risk76th percentile - higher than 76% of all known CVEs
Summary
A privilege escalation from host to domain vulnerability was found in FreeIPA. The lack of uniqueness validation for the `krbCanonicalName` attribute of the admin account allows creating a service with the same canonical name as the REALM admin. A successful attack lets the attacker obtain a Kerberos ticket with admin@REALM credentials.
Risk Assessment
An attacker can gain full control over the FreeIPA domain, performing administrative tasks, leading to access to sensitive data and data exfiltration.
Recommendation
Immediately update FreeIPA to a patched version. As a temporary workaround, manually verify the uniqueness of `krbCanonicalName` for admin accounts.
Original NVD description (English source)
A privilege escalation from host to domain vulnerability was found in the FreeIPA project. The FreeIPA package fails to validate the uniqueness of the `krbCanonicalName` for the admin account by default, allowing users to create services with the same canonical name as the REALM admin. When a successful attack happens, the user can retrieve a Kerberos ticket in the name of this service, containing the admin@REALM credential. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.
