CVE-2021-1129

Estado: ModificadaMedia (5.3)—

A vulnerability in the authentication for the general purpose APIs implementation of Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA), and Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to access general system information and certain configuration information from an affected device. The vulnerability exists because a secure authentication token is not required when authenticating to the general purpose API.

Leer descripción completaMostrar menos

An attacker could exploit this vulnerability by sending a crafted request for information to the general purpose API on an affected device. A successful exploit could allow the attacker to obtain system and configuration information from the affected device, resulting in an unauthorized information disclosure.

La vulnerabilidad se presenta porque no se requiere un token de autenticación seguro al autenticarse en la API de propósito general. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada para información de la API de propósito general en un dispositivo afectado. Una explotación con éxito podría permitir al atacante obtener información del sistema y la configuración del dispositivo afectado, resultando en una divulgación de información no autorizada"
