Descriptions

The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity.

El DC de Samba AD incluye comprobaciones cuando son añadidos nombres de directores de servicio (SPN) a una cuenta para asegurar que los SPN no presentan alias con los que ya están en la base de datos. Algunas de estas comprobaciones pueden omitirse si una modificación de la cuenta vuelve a añadir un SPN que ya estaba presente en esa cuenta, como uno añadido cuando un equipo es unido a un dominio. Un atacante que tenga la capacidad de escribir en una cuenta puede aprovechar esto para llevar a cabo un ataque de denegación de servicio al añadir un SPN que coincida con un servicio existente. Además, un atacante que pueda interceptar el tráfico puede hacerse pasar por los servicios existentes, resultando en una pérdida de confidencialidad e integridad
