CVE-2022-20940
https://notcve.org/view.php?id=CVE-2022-20940
A vulnerability in the TLS handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to gain access to sensitive information. This vulnerability is due to improper implementation of countermeasures against a Bleichenbacher attack on a device that uses SSL decryption policies. An attacker could exploit this vulnerability by sending crafted TLS messages to an affected device, which would act as an oracle and allow the attacker to carry out a chosen-ciphertext attack. A successful exploit could allow the attacker to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions to the affected device. Una vulnerabilidad en el controlador TLS del software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado obtenga acceso a información confidencial. Esta vulnerabilidad se debe a la implementación inadecuada de contramedidas contra un ataque Bleichenbacher en un dispositivo que utiliza políticas de descifrado SSL. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-tls-bb-rCgtmY2 • CWE-203: Observable Discrepancy •
CVE-2022-20928
https://notcve.org/view.php?id=CVE-2022-20928
A vulnerability in the authentication and authorization flows for VPN connections in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to establish a connection as a different user. This vulnerability is due to a flaw in the authorization verifications during the VPN authentication flow. An attacker could exploit this vulnerability by sending a crafted packet during a VPN authentication. The attacker must have valid credentials to establish a VPN connection. A successful exploit could allow the attacker to establish a VPN connection with access privileges from a different user. Una vulnerabilidad en los flujos de autenticación y autorización para conexiones VPN en el software Cisco Adaptive Security Appliance (ASA) y el software Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado establezca una conexión como un usuario diferente. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-vp-authz-N2GckjN6 • CWE-863: Incorrect Authorization •
CVE-2022-20934
https://notcve.org/view.php?id=CVE-2022-20934
A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software and Cisco FXOS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as root. This vulnerability is due to improper input validation for specific CLI commands. An attacker could exploit this vulnerability by injecting operating system commands into a legitimate command. A successful exploit could allow the attacker to escape the restricted command prompt and execute arbitrary commands on the underlying operating system. To successfully exploit this vulnerability, an attacker would need valid Administrator credentials. Una vulnerabilidad en la CLI del software Cisco Firepower Threat Defense (FTD) y el software Cisco FXOS podría permitir que un atacante local autenticado ejecute comandos arbitrarios en el Sistema Operativo subyacente como root. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-fxos-cmd-inj-Q9bLNsrK • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2022-20949
https://notcve.org/view.php?id=CVE-2022-20949
A vulnerability in the management web server of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker with high privileges to execute configuration commands on an affected system. This vulnerability exists because access to HTTPS endpoints is not properly restricted on an affected device. An attacker could exploit this vulnerability by sending specific messages to the affected HTTPS handler. A successful exploit could allow the attacker to perform configuration changes on the affected system, which should be configured and managed only through Cisco Firepower Management Center (FMC) Software. Una vulnerabilidad en el servidor web de administración del software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto autenticado con altos privilegios ejecute comandos de configuración en un sistema afectado. Esta vulnerabilidad existe porque el acceso a los endpoint HTTPS no está restringido adecuadamente en un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-mgmt-privesc-7GqR2th • CWE-399: Resource Management Errors •
CVE-2022-20854
https://notcve.org/view.php?id=CVE-2022-20854
A vulnerability in the processing of SSH connections of Cisco Firepower Management Center (FMC) 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 improper error handling when an SSH session fails to be established. An attacker could exploit this vulnerability by sending a high rate of crafted SSH connections to the instance. A successful exploit could allow the attacker to cause resource exhaustion, resulting in a reboot on the affected device. Una vulnerabilidad en el procesamiento de conexiones SSH de Cisco Firepower Management Center (FMC) 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. Esta vulnerabilidad se debe a un manejo inadecuado de errores cuando no se puede establecer una sesión SSH. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-dos-OwEunWJN • CWE-400: Uncontrolled Resource Consumption CWE-755: Improper Handling of Exceptional Conditions •
