CVE-2024-20265

A vulnerability in the boot process of Cisco Access Point (AP) Software could allow an unauthenticated, physical attacker to bypass the Cisco Secure Boot functionality and load a software image that has been tampered with on an affected device. This vulnerability exists because unnecessary commands are available during boot time at the physical console. An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised.

Summary
  • (es) Una vulnerabilidad en el proceso de arranque del software Cisco Access Point (AP) podría permitir que un atacante físico no autenticado omita la funcionalidad de arranque seguro de Cisco y cargue una imagen de software que ha sido manipulada en un dispositivo afectado. Esta vulnerabilidad existe porque hay comandos innecesarios disponibles durante el tiempo de arranque en la consola física. Un atacante podría aprovechar esta vulnerabilidad interrumpiendo el proceso de arranque y ejecutando comandos específicos para eludir las comprobaciones de validación de arranque seguro de Cisco y cargar una imagen que ha sido manipulada. Esta imagen se habría descargado previamente en el dispositivo de destino. Un exploit exitoso podría permitir al atacante cargar la imagen una vez. La funcionalidad Cisco Secure Boot no se ve comprometida permanentemente.
