CVE-2019-1721 – Cisco Expressway Series and Cisco TelePresence Video Communication Server Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1721
A vulnerability in the phone book feature 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 Session Initiation Protocol (SIP) message with a crafted XML payload to an affected device. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition. Manual intervention may be required to recover the device. • http://www.securityfocus.com/bid/108016 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-es-tvcs-dos • CWE-20: Improper Input Validation •
CVE-2019-1722 – Cisco Expressway Series and Cisco TelePresence Video Communication Server Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-1722
A vulnerability in the FindMe feature of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. The arbitrary actions include adding an attacker-controlled device and redirecting calls intended for a specific user. • http://www.securityfocus.com/bid/108006 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-ex-vcs-xsrf • CWE-352: Cross-Site Request Forgery (CSRF) •
CVE-2019-1679 – Cisco TelePresence Conductor, Cisco Expressway Series, and Cisco TelePresence Video Communication Server REST API Server-Side Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-1679
A vulnerability in the web interface of Cisco TelePresence Conductor, Cisco Expressway Series, and Cisco TelePresence Video Communication Server (VCS) Software could allow an authenticated, remote attacker to trigger an HTTP request from an affected server to an arbitrary host. This type of attack is commonly referred to as server-side request forgery (SSRF). The vulnerability is due to insufficient access controls for the REST API of Cisco Expressway Series and Cisco TelePresence VCS. An attacker could exploit this vulnerability by submitting a crafted HTTP request to the affected server. Versions prior to XC4.3.4 are affected. • http://www.securityfocus.com/bid/106940 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190206-rest-api-ssrf • CWE-918: Server-Side Request Forgery (SSRF) •
