Descriptions

A vulnerability in Session Initiation Protocol (SIP) call handling in Cisco IP Phone 8800 Series devices could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition because the SIP process unexpectedly restarts. All active phone calls are dropped as the SIP process restarts. The vulnerability is due to incomplete input validation of the SIP packet header. An attacker could exploit this vulnerability by sending a malformed SIP packet to a targeted phone. An exploit could allow the attacker to cause a DoS condition because all phone calls are dropped when the SIP process unexpectedly restarts. Cisco Bug IDs: CSCvc62590.

Una vulnerabilidad en la manipulación de llamadas SIP (Session Initiation Protocol) de los dispositivos de la serie 8800 de Cisco IP Phone podría permitir que un atacante remoto no autenticado provoque una denegación de servicio (DoS) porque el proceso SIP se reinicia de manera inesperada. Todas las llamadas telefónicas activas se colgarían al reiniciarse el proceso SIP. Esta vulnerabilidad se debe a la incompleta validación de entradas de la cabecera de los paquetes SIP. Un atacante podría explotar esta vulnerabilidad enviando un paquete SIP mal formado al teléfono objetivo. El atacante podría utilizar un exploit para provocar una denegación de servicio (DoS) porque todas las llamadas telefónicas se cuelgan cuando el proceso SIP se reinicia de manera inesperada. Cisco Bug IDs: CSCvc62590.
