CVE-2026-20041
Full vulnerability record from the local CVENow database.
Description
A vulnerability in Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights could allow an unauthenticated, remote attacker to conduct a server-side request forgery (SSRF) attack through an affected device. This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by persuading an authenticated user of the device management interface to click a crafted link. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected device to an attacker-controlled server. The attacker could then execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

"value": "Una vulnerabilidad en Cisco Nexus Dashboard y Cisco Nexus Dashboard Insights podría permitir a un atacante remoto no autenticado realizar un ataque de falsificación de petición del lado del servidor (SSRF) a través de un dispositivo afectado.\n\nEsta vulnerabilidad se debe a una validación de entrada incorrecta para peticiones HTTP específicas. Un atacante podría explotar esta vulnerabilidad al persuadir a un usuario autenticado de la interfaz de gestión del dispositivo para que haga clic en un enlace manipulado. Un exploit exitoso podría permitir al atacante enviar peticiones de red arbitrarias que se originan en el dispositivo afectado a un servidor controlado por el atacante. El atacante podría entonces ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información sensible basada en el navegador."
