CVE-2026-13097
Full vulnerability record from the local CVENow database.
Description
A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one. This can lead to unauthorized acquisition of Kerberos service tickets for sensitive services, potentially resulting in full domain compromise.

"value": "Se encontró una vulnerabilidad de escalada de privilegios en FreeIPA. La restricción de unicidad aplicada a los atributos de nombre de principal de Kerberos en el servidor de directorio 389-ds no tiene en cuenta adecuadamente las representaciones equivalentes del mismo nombre de principal, permitiendo a un usuario con suficientes privilegios de escritura LDAP crear un principal de servicio que suplanta a uno privilegiado existente. Esto puede llevar a la adquisición no autorizada de tickets de servicio de Kerberos para servicios sensibles, lo que podría resultar en un compromiso total del dominio."
