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 •
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 •
