      "value": "CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated command injection vulnerability in the remote backup transfer feature that allows authenticated attackers to execute arbitrary OS commands by controlling a remote server's API response. Attackers can inject malicious commands through a crafted directory name in the remote server's API response, which bypasses security middleware validation and is passed unsanitized to the OS command execution function."

      "value": "CyberPanel 2.4.3, corregida en el commit eca0c3c, contiene una vulnerabilidad de inyección de comandos autenticada en la función de transferencia de copia de seguridad remota que permite a atacantes autenticados ejecutar comandos arbitrarios del sistema operativo controlando la respuesta de la API de un servidor remoto. Los atacantes pueden inyectar comandos maliciosos a través de un nombre de directorio manipulado en la respuesta de la API del servidor remoto, lo que elude la validación del middleware de seguridad y se pasa sin sanear a la función de ejecución de comandos del sistema operativo."
