Vulnerability from fkie_nvd - Published: 2024-03-27 17:15 - Updated: 2024-11-21 08:52
Severity ?
5.9 (Medium) - CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
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.

Esta vulnerabilidad existe porque hay comandos innecesarios disponibles durante el tiempo de arranque en la consola f\u00edsica. Un atacante podr\u00eda aprovechar esta vulnerabilidad interrumpiendo el proceso de arranque y ejecutando comandos espec\u00edficos para eludir las comprobaciones de validaci\u00f3n de arranque seguro de Cisco y cargar una imagen que ha sido manipulada. Esta imagen se habr\u00eda descargado previamente en el dispositivo de destino. Un exploit exitoso podr\u00eda permitir al atacante cargar la imagen una vez. La funcionalidad Cisco Secure Boot no se ve comprometida permanentemente."
