CVSS: 6.5EPSS: 0%CPEs: 25EXPL: 0CVE-2021-40125 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software IKEv2 Site-to-Site VPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-40125
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. This vulnerability is due to improper control of a resource. An attacker with the ability to spoof a trusted IKEv2 site-to-site VPN peer and in possession of valid IKEv2 credentials for that peer could exploit this vulnerability by sending malformed, authenticated IKEv2 messages to an affected device. A successful exploit could allow the attacker to trigger a reload of the device. Una vulnerabilidad en la implementación del Intercambio de Claves de Internet Versión 2 (IKEv2) del software Cisco Adaptive Security Appliance (ASA) y del software Cisco Firepower Threat Defense (FTD) podría permitir a un atacante remoto autenticado desencadenar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-ikev2-dos-g4cmrr7C • CWE-400: Uncontrolled Resource Consumption CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2021-1504
Multiple vulnerabilities in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to lack of proper input validation of the HTTPS request. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: This vulnerability affects only specific AnyConnect and WebVPN configurations. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-vpn-dos-fpBcpEcD • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-1501
A vulnerability in the SIP inspection engine of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a crash and reload of an affected device, resulting in a denial of service (DoS) condition.The vulnerability is due to a crash that occurs during a hash lookup for a SIP pinhole connection. An attacker could exploit this vulnerability by sending crafted SIP traffic through an affected device. A successful exploit could allow the attacker to cause a crash and reload of the affected device. Una vulnerabilidad en el motor de inspección SIP del Software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto no autenticado causar un bloqueo y la recarga de un dispositivo afectado, resultando en una denegación de servicio ( DoS). La vulnerabilidad es debido a un bloqueo que ocurre durante una búsqueda de hash para una conexión SIP pinhole. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-sipdos-GGwmMerC • CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2021-1493
A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a buffer overflow on an affected system. The 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 malicious HTTP request. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could disclose data fragments or cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la interfaz de servicios web del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto autenticado causar un desbordamiento del búfer en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-memc-dos-fncTyYKG • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
