Se he encontrado una vulnerabilidad de tipo desbordamiento de búfer en Cisco Unified Communications Manager (CUCM). La vulnerabilidad reside en un error en la comprovación de límites en el Proveedor de servicio CTL (Certificate Trust List) CTLProvider.exe. Un atacante remoto podría causar una denegación de servicio o ejecutar código arbitrario mediante el envío de un paquete especialmente diseñado al puerto 2444/TCP. |
