CVE-2024-20316

A vulnerability in the data model interface (DMI) services of Cisco IOS XE Software could allow an unauthenticated, remote attacker to access resources that should have been protected by a configured IPv4 access control list (ACL). This vulnerability is due to improper handling of error conditions when a successfully authorized device administrator updates an IPv4 ACL using the NETCONF or RESTCONF protocol, and the update would reorder access control entries (ACEs) in the updated ACL. An attacker could exploit this vulnerability by accessing resources that should have been protected across an affected device.
Configurations

Summary
  • (es) Una vulnerabilidad en los servicios de interfaz de modelo de datos (DMI) del software Cisco IOS XE podría permitir que un atacante remoto no autenticado acceda a recursos que deberían haber estado protegidos por una lista de control de acceso (ACL) IPv4 configurada. Esta vulnerabilidad se debe al manejo inadecuado de las condiciones de error cuando un administrador de dispositivo autorizado exitosamente actualiza una ACL IPv4 usando el protocolo NETCONF o RESTCONF, y la actualización reordenaría las entradas de control de acceso (ACE) en la ACL actualizada. Un atacante podría aprovechar esta vulnerabilidad accediendo a recursos que deberían haber estado protegidos en un dispositivo afectado.
