CVE-2026-76488
Una vulnerabilidad en la funcionalidad de políticas de exportación de Cisco Application Policy Infrastructure Controller (APIC) podría permitir a un atacante remoto autenticado acceder a archivos sensibles en un dispositivo afectado. Para explotar esta vulnerabilidad, el atacante debe tener credenciales administrativas válidas.
Esta vulnerabilidad se debe a un control de acceso insuficiente a los recursos del sistema de archivos. Un atacante podría explotar esta vulnerabilidad enviando valores manipulados en campos específicos de la interfaz de usuario.
Leer descripción completaMostrar menos
Una explotación con éxito podría permitir al atacante acceder a archivos sensibles del sistema de archivos subyacente de un dispositivo afectado, incluido material de claves que podría utilizarse para elevar privilegios a root en el APIC afectado y en los switches gestionados.
