CVE-2025-20251 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2026-04-15 8.5 High
A vulnerability in the Remote Access SSL VPN service for Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker to create or delete arbitrary files on the underlying operating system. If critical system files are manipulated, new Remote Access SSL VPN sessions could be denied and existing sessions could be dropped, causing a denial of service (DoS) condition. An exploited device requires a manual reboot to recover. This vulnerability is due to insufficient input validation when processing HTTP requests. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to create or delete files on the underlying operating system, which could cause the Remote Access SSL VPN service to become unresponsive. To exploit this vulnerability, the attacker must be authenticated as a VPN user of the affected device.
CVE-2025-20263 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2026-04-15 8.6 High
A vulnerability in the web services interface of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected system.  This vulnerability is due to insufficient boundary checks for specific data that is provided to the web services interface of an affected system. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could cause the system to reload, resulting in a denial of service (DoS) condition.
CVE-2025-20134 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2026-04-15 8.6 High
A vulnerability in the certificate processing of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper parsing of SSL/TLS certificates. An attacker could exploit this vulnerability by sending crafted DNS packets that match a static Network Address Translation (NAT) rule with DNS inspection enabled through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
CVE-2025-20268 1 Cisco 1 Firepower Threat Defense Software 2026-04-15 5.8 Medium
A vulnerability in the Geolocation-Based Remote Access (RA) VPN feature of Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured policies to allow or deny HTTP connections based on a country or region. This vulnerability exists because the URL string is not fully parsed. An attacker could exploit this vulnerability by sending a crafted HTTP connection through the targeted device. A successful exploit could allow the attacker to bypass configured policies and gain access to a network where the connection should have been denied.
CVE-2025-20243 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2026-04-15 8.6 High
A vulnerability in the management and VPN web servers of Cisco Secure Firewall ASA Software and Secure FTD Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a DoS condition. This vulnerability is due to improper validation of user-supplied input on an interface with VPN web services. An attacker could exploit this vulnerability by sending crafted HTTP requests to a targeted web server on an affected device. A successful exploit could allow the attacker to cause a DoS condition when the device reloads.
CVE-2025-20238 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2026-04-15 6 Medium
A vulnerability in Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system with root-level privileges. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to insufficient input validation of commands that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input for specific commands. A successful exploit could allow the attacker to execute commands on the underlying operating system as root.
CVE-2025-20292 1 Cisco 2 Nx-os, Unified Computing System Manager 2026-04-15 4.4 Medium
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute a command injection attack on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have valid user credentials on the affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted input as the argument of an affected CLI command. A successful exploit could allow the attacker to read and write files on the underlying operating system with the privileges of a non-root user account. File system access is limited to the permissions that are granted to that non-root user account.
CVE-2025-20239 1 Cisco 5 Adaptive Security Appliance Software, Firepower Threat Defense Software, Ios and 2 more 2026-04-15 8.6 High
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) feature of Cisco IOS Software, IOS XE Software, Secure Firewall Adaptive Security Appliance (ASA) Software, and Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a memory leak, resulting in a denial of service (DoS) condition. This vulnerability is due to a lack of proper processing of IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device. In the case of Cisco IOS and IOS XE Software, a successful exploit could allow the attacker to cause the device to reload unexpectedly. In the case of Cisco ASA and FTD Software, a successful exploit could allow the attacker to partially exhaust system memory, causing system instability such as being unable to establish new IKEv2 VPN sessions. A manual reboot of the device is required to recover from this condition.
