CVE-2020-3189 – Cisco Firepower Threat Defense Software VPN System Logging Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3189
06 May 2020 — A vulnerability in the VPN System Logging functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak that can deplete system memory over time, which can cause unexpected system behaviors or device crashes. The vulnerability is due to the system memory not being properly freed for a VPN System Logging event generated when a VPN session is created or deleted. An attacker could exploit this vulnerability by repeatedly creating or delet... • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-dos-Rdpe34sd8 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2020-3188 – Cisco Firepower Threat Defense Software Management Interface Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3188
06 May 2020 — A vulnerability in how Cisco Firepower Threat Defense (FTD) Software handles session timeouts for management connections could allow an unauthenticated, remote attacker to cause a buildup of remote management connections to an affected device, which could result in a denial of service (DoS) condition. The vulnerability exists because the default session timeout period for specific to-the-box remote management connections is too long. An attacker could exploit this vulnerability by sending a large and sustai... • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-mgmt-interface-dos-FkG4MuTU • CWE-399: Resource Management Errors CWE-613: Insufficient Session Expiration •

CVE-2020-3179 – Cisco Firepower Threat Defense Software Generic Routing Encapsulation Tunnel IPv6 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3179
06 May 2020 — A vulnerability in the generic routing encapsulation (GRE) tunnel decapsulation feature of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory handling error when GRE over IPv6 traffic is processed. An attacker could exploit this vulnerability by sending crafted GRE over IPv6 packets with either IPv4 or IPv6 payload through an affected device. A successful exploi... • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-dos-2-sS2h7aWe • CWE-415: Double Free •
