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: 9.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-1716 – Cisco IP Phone 7800 Series and 8800 Series Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2019-1716
A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code. The vulnerability exists because the software improperly validates user-supplied input during user authentication. An attacker could exploit this vulnerability by connecting to an affected device using HTTP and supplying malicious user credentials. A successful exploit could allow the attacker to trigger a reload of an affected device, resulting in a DoS condition, or to execute arbitrary code with the privileges of the app user. Cisco fixed this vulnerability in the following SIP Software releases: 10.3(1)SR5 and later for Cisco Unified IP Conference Phone 8831; 11.0(4)SR3 and later for Cisco Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 and later for the rest of the Cisco IP Phone 7800 Series and 8800 Series. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190320-ip-phone-rce • CWE-20: Improper Input Validation •
