CVE-2020-3529 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SSL VPN Direct Memory Access Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3529
A vulnerability in the SSL VPN negotiation process for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient direct memory access (DMA) memory management during the negotiation phase of an SSL VPN connection. An attacker could exploit this vulnerability by sending a steady stream of crafted Datagram TLS (DTLS) traffic to an affected device. A successful exploit could allow the attacker to exhaust DMA memory on the device and cause a DoS condition. Una vulnerabilidad en el proceso de negociación de SSL VPN para Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-sslvpndma-dos-HRrqB9Yx • CWE-400: Uncontrolled Resource Consumption •
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-2020-3452 – Cisco ASA and FTD Read-Only Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2020-3452
A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct directory traversal attacks and read sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of URLs in HTTP requests processed by an affected device. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences to an affected device. A successful exploit could allow the attacker to view arbitrary files within the web services file system on the targeted device. The web services file system is enabled when the affected device is configured with either WebVPN or AnyConnect features. • https://www.exploit-db.com/exploits/48722 https://www.exploit-db.com/exploits/49262 https://www.exploit-db.com/exploits/48871 https://github.com/darklotuskdb/CISCO-CVE-2020-3452-Scanner-Exploiter https://github.com/0x5ECF4ULT/CVE-2020-3452 https://github.com/cygenta/CVE-2020-3452 https://github.com/3ndG4me/CVE-2020-3452-Exploit https://github.com/PR3R00T/CVE-2020-3452-Cisco-Scanner https://github.com/murataydemir/CVE-2020-3452 https://github.com/grim3/CVE-2020-3452 https& • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2020-3298 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Malformed OSPF Packets Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3298
A vulnerability in the Open Shortest Path First (OSPF) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper memory protection mechanisms while processing certain OSPF packets. An attacker could exploit this vulnerability by sending a series of malformed OSPF packets in a short period of time to an affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition for client traffic that is traversing the device. Una vulnerabilidad en la implementación de Open Shortest Path First (OSPF) del Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar el reinicio de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-ospf-dos-RhMQY8qx • CWE-125: Out-of-bounds Read •
