CVE-2025-20358
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the Contact Center Express (CCX) Editor application of Cisco Unified CCX could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative permissions pertaining to script creation and execution. This vulnerability is due to improper authentication mechanisms in the communication between the CCX Editor and an affected Unified CCX server. An attacker could exploit this vulnerability by redirecting the authentication flow to a malicious server and tricking the CCX Editor into believing the authentication was successful. A successful exploit could allow the attacker to create and execute arbitrary scripts on the underlying operating system of an affected Unified CCX server, as an internal non-root user account.

"value": "Una vulnerabilidad en la aplicación Contact Center Express (CCX) Editor de Cisco Unified CCX podría permitir a un atacante remoto no autenticado eludir la autenticación y obtener permisos administrativos relacionados con la creación y ejecución de scripts.\n\nEsta vulnerabilidad se debe a mecanismos de autenticación inadecuados en la comunicación entre el CCX Editor y un servidor Unified CCX afectado. Un atacante podría explotar esta vulnerabilidad redirigiendo el flujo de autenticación a un servidor malicioso y engañando al CCX Editor para que crea que la autenticación fue exitosa. Un exploit exitoso podría permitir al atacante crear y ejecutar scripts arbitrarios en el sistema operativo subyacente de un servidor Unified CCX afectado, como una cuenta de usuario interna sin privilegios de root."
