      "value": "A path traversal vulnerability was found in the VPN Clients on the ADM. The vulnerability occurs because user-controlled certificate name input is not sufficiently validated before being used to construct the upload destination path. An authenticated attacker can exploit this issue to write an uploaded certificate file outside the intended VPN certificate directory, subject to process privileges and filesystem permissions.\nAffected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81."

      "value": "Se encontró una vulnerabilidad de salto de ruta en los Clientes VPN en el ADM. La vulnerabilidad ocurre porque la entrada del nombre del certificado controlada por el usuario no se valida suficientemente antes de ser utilizada para construir la ruta de destino de la carga. Un atacante autenticado puede explotar este problema para escribir un archivo de certificado cargado fuera del directorio de certificados VPN previsto, sujeto a los privilegios del proceso y los permisos del sistema de archivos.\nLos productos y versiones afectados incluyen: desde ADM 4.1.0 hasta ADM 4.3.3.RUN1, así como desde ADM 5.0.0 hasta ADM 5.1.3.RI81."
