CVE-2023-20018
https://notcve.org/view.php?id=CVE-2023-20018
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 •
CVE-2019-1684 – Cisco IP Phone 7800 and 8800 Series Cisco Discovery Protocol and Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1684
A vulnerability in the Cisco Discovery Protocol or Link Layer Discovery Protocol (LLDP) implementation for the Cisco IP Phone 7800 and 8800 Series could allow an unauthenticated, adjacent attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to missing length validation of certain Cisco Discovery Protocol or LLDP packet header fields. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol or LLDP packet to the targeted phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition. Versions prior to 12.6(1)MN80 are affected. • http://www.securityfocus.com/bid/107104 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-cdp-lldp-dos • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •
CVE-2018-0325
https://notcve.org/view.php?id=CVE-2018-0325
A vulnerability in the Session Initiation Protocol (SIP) call-handling functionality of Cisco IP Phone 7800 Series phones and Cisco IP Phone 8800 Series phones could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to incomplete input validation of SIP Session Description Protocol (SDP) parameters by the SDP parser of an affected phone. An attacker could exploit this vulnerability by sending a malformed SIP packet to an affected phone. A successful exploit could allow the attacker to cause all active phone calls on the affected phone to be dropped while the SIP process on the phone unexpectedly restarts, resulting in a DoS condition.
