CVE-2019-1635
Estado: ModificadaAlta (7.5)—
A vulnerability in the call-handling functionality of Session Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to incomplete error handling when XML data within a SIP packet is parsed. An attacker could exploit this vulnerability by sending a SIP packet that contains a malicious XML payload to an affected phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition.

La vulnerabilidad es debido a un manejo de errores incompleto cuando los datos XML dentro de un paquete SIP son analizados. Un atacante podría aprovechar esta vulnerabilidad enviando un paquete SIP que contiene una carga XML maliciosa a un teléfono afectado. Una operación éxito podría permitir al atacante hacer que el teléfono afectado se recargue inesperadamente, resultando en una condición DoS temporal."
