CVSS: 7.8EPSS: 0%CPEs: 80EXPL: 0CVE-2019-1635 – Cisco IP Phone 7800 Series and 8800 Series Session Initiation Protocol XML Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1635
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. Una vulnerabilidad en la funcionalidad de manejo de llamadas (call-handling) del Software Session Initiation Protocol (SIP) para teléfonos IP 7800 Series y 8800 Series de Cisco, podría permitir que un atacante remoto no identificado haga que un teléfono afectado se recargue inesperadamente, resultando en una condición de Denegación de Servicio (DoS ) temporal. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-phone-sip-xml-dos • CWE-399: Resource Management Errors CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 6.5EPSS: 0%CPEs: 28EXPL: 0CVE-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 •
