CVE-2021-34761 – Cisco Firepower Threat Defense Software CLI Arbitrary File Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-34761
A vulnerability in Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to overwrite or append arbitrary data to system files using root-level privileges. The attacker must have administrative credentials on the device. This vulnerability is due to incomplete validation of user input for a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device with administrative privileges and issuing a CLI command with crafted user parameters. A successful exploit could allow the attacker to overwrite or append arbitrary data to system files using root-level privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-file-write-SHVcmQVc • CWE-73: External Control of File Name or Path CWE-668: Exposure of Resource to Wrong Sphere •

CVE-2021-34754 – Cisco Firepower Threat Defense Software Ethernet Industrial Protocol Policy Bypass Vulnerabilities
https://notcve.org/view.php?id=CVE-2021-34754
Multiple vulnerabilities in the payload inspection for Ethernet Industrial Protocol (ENIP) traffic for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured rules for ENIP traffic. These vulnerabilities are due to incomplete processing during deep packet inspection for ENIP packets. An attacker could exploit these vulnerabilities by sending a crafted ENIP packet to the targeted interface. A successful exploit could allow the attacker to bypass configured access control and intrusion policies that should be activated for the ENIP packet. Múltiples vulnerabilidades en la inspección de la carga útil del tráfico del Protocolo Industrial Ethernet (ENIP) para el software Cisco Firepower Threat Defense (FTD) podrían permitir a un atacante remoto no autenticado omitir las reglas configuradas para el tráfico ENIP. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-enip-bypass-eFsxd8KP • CWE-284: Improper Access Control •
CVE-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 •
