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: 8.6EPSS: 0%CPEs: 8EXPL: 0CVE-2021-1445 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Web Services VPN Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2021-1445
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 •
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 •
CVSS: 8.6EPSS: 0%CPEs: 17EXPL: 0CVE-2021-1402 – Cisco Firepower Threat Defense Software SSL Decryption Policy Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1402
A vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-ssl-decrypt-dos-DdyLuK6c • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.3EPSS: 0%CPEs: 23EXPL: 0CVE-2021-1236 – Multiple Cisco Products Snort Application Detection Engine Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1236
Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección de aplicaciones de Snort que podría permitir a un atacante remoto no autenticado omitir las políticas configuradas en un sistema afectado. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-app-bypass-cSBYCATq https://www.debian.org/security/2023/dsa-5354 • CWE-670: Always-Incorrect Control Flow Implementation •
