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') •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2021-1448 – Cisco Firepower Threat Defense Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1448
A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges on the underlying operating system of an affected device that is running in multi-instance mode. This vulnerability is due to insufficient validation of user-supplied command arguments. An attacker could exploit this vulnerability by submitting crafted input to the affected command. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges. Una vulnerabilidad en la CLI del software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante autenticado local ejecutar comandos arbitrarios con privilegios root en el sistema operativo subyacente de un dispositivo afectado que es ejecutado en modo multi-instance. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-cmdinj-vWY5wqZT • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.0EPSS: 0%CPEs: 2EXPL: 0CVE-2021-1256 – Cisco Firepower Threat Defense Software Command File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2021-1256
A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to overwrite files on the file system of an affected device by using directory traversal techniques. A successful exploit could cause system instability if important system files are overwritten. This vulnerability is due to insufficient validation of user input for the file path in a specific CLI command. An attacker could exploit this vulnerability by logging in to a targeted device and issuing a specific CLI command with crafted user input. A successful exploit could allow the attacker to overwrite arbitrary files on the file system of the affected device. • https://kc.mcafee.com/corporate/index?page=content&id=SB10382 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-file-overwrite-XknRjGdB • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-552: Files or Directories Accessible to External Parties •
