CVE-2025-20376

A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to upload and execute arbitrary files. This vulnerability is due to an insufficient input validation associated to file upload mechanisms. An attacker could exploit this vulnerability by uploading a malicious file to the web UI and executing it. A successful exploit could allow the attacker to execute arbitrary commands on the underlying system and elevate privileges to root. To exploit this vulnerability, the attacker must have valid administrative credentials.

Summary		(es) Una vulnerabilidad en la interfaz de usuario web de Cisco Unified CCX podría permitir a un atacante remoto autenticado cargar y ejecutar archivos arbitrarios. Esta vulnerabilidad se debe a una validación de entrada insuficiente asociada a los mecanismos de carga de archivos. Un atacante podría explotar esta vulnerabilidad cargando un archivo malicioso en la interfaz de usuario web y ejecutándolo. Un exploit exitoso podría permitir al atacante ejecutar comandos arbitrarios en el sistema subyacente y elevar privilegios a root. Para explotar esta vulnerabilidad, el atacante debe tener credenciales administrativas válidas.
