CVE-2020-3533 – Cisco Firepower Threat Defense Software SNMP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3533
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly. The vulnerability is due to a lack of sufficient memory management protections under heavy SNMP polling loads. An attacker could exploit this vulnerability by sending a high rate of SNMP requests to the SNMP daemon through the management interface on an affected device. A successful exploit could allow the attacker to cause the SNMP daemon process to consume a large amount of system memory over time, which could then lead to an unexpected device restart, causing a denial of service (DoS) condition. This vulnerability affects all versions of SNMP. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-snmp-dos-R8ENPbOs • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-3549 – Cisco Firepower Management Center Software and Firepower Threat Defense Software sftunnel Pass the Hash Vulnerability
https://notcve.org/view.php?id=CVE-2020-3549
A vulnerability in the sftunnel functionality of Cisco Firepower Management Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to obtain the device registration hash. The vulnerability is due to insufficient sftunnel negotiation protection during initial device registration. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a specific flow of the sftunnel communication between an FMC device and an FTD device. A successful exploit could allow the attacker to decrypt and modify the sftunnel communication between FMC and FTD devices, allowing the attacker to modify configuration data sent from an FMC device to an FTD device or alert data sent from an FTD device to an FMC device. Una vulnerabilidad en la funcionalidad sftunnel de Cisco Firepower Management Center (FMC) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado obtener el hash de registro del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftdfmc-sft-mitm-tc8AzFs2 • CWE-326: Inadequate Encryption Strength •
CVE-2020-3550 – Cisco Firepower Management Center Software and Firepower Threat Defense Software Directory Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2020-3550
A vulnerability in the sfmgr daemon of Cisco Firepower Management Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to perform directory traversal and access directories outside the restricted path. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by using a relative path in specific sfmgr commands. An exploit could allow the attacker to read or write arbitrary files on an sftunnel-connected peer device. Una vulnerabilidad en el demonio sfmgr de Cisco Firepower Management Center (FMC) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto autenticado llevar a cabo un salto de directorio y acceder a directorios fuera de la ruta restringida. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftdfmc-dirtrav-NW8XcuSB • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2020-3299 – Multiple Cisco Products SNORT HTTP Detection Engine File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3299
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured File Policy for HTTP. The vulnerability is due to incorrect detection of modified HTTP packets used in chunked responses. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured File Policy for HTTP packets and deliver a malicious payload. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección de Snort que podría permitir a un atacante remoto no autenticado omitir una Política de Archivos configurada para HTTP. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-bypass-3eCfd24j https://www.debian.org/security/2023/dsa-5354 • CWE-693: Protection Mechanism Failure •
CVE-2020-3308 – Cisco Firepower Threat Defense Software Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3308
A vulnerability in the Image Signature Verification feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker with administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. Una vulnerabilidad en la funcionalidad Image Signature Verification del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto autenticado con credenciales de nivel de administrador instalar un parche de software malicioso sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sigbypass-FcvPPCeP • CWE-347: Improper Verification of Cryptographic Signature •
