CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-3596 – Cisco Expressway Series and TelePresence Video Communication Server Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3596
A vulnerability in the Session Initiation Protocol (SIP) of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect handling of incoming SIP traffic. An attacker could exploit this vulnerability by sending a series of SIP packets to an affected device. A successful exploit could allow the attacker to exhaust memory on an affected device, causing it to crash and leading to a DoS condition. Una vulnerabilidad en el Session Initiation Protocol (SIP) de Cisco Expressway Series y Cisco TelePresence Video Communication Server (VCS), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-expressway-vcs-dos-n6xxTMZB • CWE-670: Always-Incorrect Control Flow Implementation CWE-789: Memory Allocation with Excessive Size Value •

https://notcve.org/view.php?id=CVE-2019-12705
A vulnerability in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Expressway Series y Cisco TelePresence Video Communication Server (VCS), podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz de administración basada en web de un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-vcs-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2019-1720
A vulnerability in the XML API of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to cause the CPU to increase to 100% utilization, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to improper handling of the XML input. An attacker could exploit this vulnerability by sending a specifically crafted XML payload. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition until the system is manually rebooted. Software versions prior to X12.5.1 are affected. • http://www.securityfocus.com/bid/108002 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-ces-tvcs-dos • CWE-20: Improper Input Validation •
