A vulnerability in the web-based management interface of Cisco IP Phone 7800 and 8800 Series Phones could allow an unauthenticated, remote attacker to bypass authentication on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to access certain parts of the web interface that would normally require authentication. Una vulnerabilidad en la interfaz de administración basada en web de los teléfonos Cisco IP Phone de las series 7800 y 8800 podría permitir que un atacante remoto no autenticado omita la autenticación en un dispositivo afectado. Esta vulnerabilidad se debe a una validación insuficiente de la entrada proporcionada por el usuario. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ip-phone-auth-bypass-pSqxZRPR • CWE-288: Authentication Bypass Using an Alternate Path or Channel CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2019-1922
A vulnerability in Cisco SIP IP Phone Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to insufficient validation of input Session Initiation Protocol (SIP) packets. An attacker could exploit this vulnerability by altering the SIP replies that are sent to the affected phone during the registration process. A successful exploit could allow the attacker to cause the phone to reboot and not complete the registration process. Una vulnerabilidad en el software SIP IP Phone de Cisco para IP Phone 7800 Series y 8800 Series de Cisco, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un teléfono afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-ip-phone-sip-dos • CWE-476: NULL Pointer Dereference •
