CVE-2023-20247
https://notcve.org/view.php?id=CVE-2023-20247
A vulnerability in the remote access SSL VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to bypass a configured multiple certificate authentication policy and connect using only a valid username and password. This vulnerability is due to improper error handling during remote access VPN authentication. An attacker could exploit this vulnerability by sending crafted requests during remote access VPN session establishment. A successful exploit could allow the attacker to bypass the configured multiple certificate authentication policy while retaining the privileges and permissions associated with the original connection profile. Una vulnerabilidad en la función VPN SSL de acceso remoto del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD) podría permitir a un atacante remoto autenticado omita una política de autenticación de múltiples certificados configurada y conectarse usando solo un nombre de usuario válido y contraseña. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-multi-cert-dzA3h5PT • CWE-288: Authentication Bypass Using an Alternate Path or Channel •
CVE-2023-20246
https://notcve.org/view.php?id=CVE-2023-20246
Multiple Cisco products are affected by a vulnerability in Snort access control policies that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. This vulnerability is due to a logic error that occurs when the access control policies are being populated. An attacker could exploit this vulnerability by establishing a connection to an affected device. A successful exploit could allow the attacker to bypass configured access control rules on the affected system. Varios productos de Cisco se ven afectados por una vulnerabilidad en las políticas de control de acceso de Snort que podría permitir que un atacante remoto no autenticado eluda las políticas configuradas en un sistema afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-snort3acp-bypass-3bdR2BEh • CWE-290: Authentication Bypass by Spoofing •
CVE-2023-20063 – Cisco Cisco Firepower Threat Defense Software and Cisco Firepower Management Center Code Injection Vulnerability
https://notcve.org/view.php?id=CVE-2023-20063
A vulnerability in the inter-device communication mechanisms between devices that are running Cisco Firepower Threat Defense (FTD) Software and devices that are running Cisco Firepower Management (FMC) Software could allow an authenticated, local attacker to execute arbitrary commands with root permissions on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by accessing the expert mode of an affected device and submitting specific commands to a connected system. A successful exploit could allow the attacker to execute arbitrary code in the context of an FMC device if the attacker has administrative privileges on an associated FTD device. Alternatively, a successful exploit could allow the attacker to execute arbitrary code in the context of an FTD device if the attacker has administrative privileges on an associated FMC device. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-fmc-code-inj-wSHrgz8L • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVE-2023-20042
https://notcve.org/view.php?id=CVE-2023-20042
A vulnerability in the AnyConnect SSL VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an implementation error within the SSL/TLS session handling process that can prevent the release of a session handler under specific conditions. An attacker could exploit this vulnerability by sending crafted SSL/TLS traffic to an affected device, increasing the probability of session handler leaks. A successful exploit could allow the attacker to eventually deplete the available session handler pool, preventing new sessions from being established and causing a DoS condition. Una vulnerabilidad en la función AnyConnect SSL VPN del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado cause una condición de Denegación de Servicio (DoS) en un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-ssl-dos-kxG8mpUA • CWE-404: Improper Resource Shutdown or Release •
CVE-2023-20070
https://notcve.org/view.php?id=CVE-2023-20070
A vulnerability in the TLS 1.3 implementation of the Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the Snort 3 detection engine to unexpectedly restart. This vulnerability is due to a logic error in how memory allocations are handled during a TLS 1.3 session. Under specific, time-based constraints, an attacker could exploit this vulnerability by sending a crafted TLS 1.3 message sequence through an affected device. A successful exploit could allow the attacker to cause the Snort 3 detection engine to reload, resulting in a denial of service (DoS) condition. While the Snort detection engine reloads, packets going through the FTD device that are sent to the Snort detection engine will be dropped. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-snort3-uAnUntcV • CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection') •
