CVE-2026-20200
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with low privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.

"value": "Una vulnerabilidad en la interfaz de gestión basada en web de Cisco IMC podría permitir a un atacante remoto autenticado con privilegios bajos ejecutar comandos arbitrarios en el sistema operativo subyacente de un sistema afectado y elevar privilegios a root.\n\nEsta vulnerabilidad se debe a una validación incorrecta de la entrada proporcionada por el usuario. Un atacante podría explotar esta vulnerabilidad introduciendo entradas manipuladas en la interfaz de gestión basada en web del software afectado. Un exploit exitoso podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente como el usuario root."
