CVE-2020-3552 – Cisco Aironet Access Points Ethernet Wired Clients Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3552
A vulnerability in the Ethernet packet handling of Cisco Aironet Access Points (APs) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by connecting as a wired client to the Ethernet interface of an affected device and sending a series of specific packets within a short time frame. A successful exploit could allow the attacker to cause a NULL pointer access that results in a reload of the affected device. Una vulnerabilidad en el manejo de paquetes Ethernet de Cisco Aironet Access Points (APs) Software, podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-ethport-dos-xtjTt8pY • CWE-476: NULL Pointer Dereference •
CVE-2020-3559 – Cisco Aironet Access Point Authentication Flood Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3559
A vulnerability in Cisco Aironet Access Point (AP) Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper handling of clients that are trying to connect to the AP. An attacker could exploit this vulnerability by sending authentication requests from multiple clients to an affected device. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en Cisco Aironet Access Point (AP) Software, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-dos-h3DCuLXw • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-3560 – Cisco Aironet Access Points UDP Flooding Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3560
A vulnerability in Cisco Aironet Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) on an affected device. The vulnerability is due to improper resource management while processing specific packets. An attacker could exploit this vulnerability by sending a series of crafted UDP packets to a specific port on an affected device. A successful exploit could either allow the attacker to tear down the connection between the AP and the wireless LAN controller, resulting in the affected device not being able to process client traffic, or cause the vulnerable device to reload, triggering a DoS condition. After the attack, the affected device should automatically recover its normal functions without manual intervention. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-dos-VHr2zG9y • CWE-400: Uncontrolled Resource Consumption •
CVE-2019-1649 – Cisco Secure Boot Hardware Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2019-1649
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. • http://www.securityfocus.com/bid/108350 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot https://www.kb.cert.org/vuls/id/400865 https://www.us-cert.gov/ics/advisories/icsa-20-072-03 • CWE-284: Improper Access Control CWE-667: Improper Locking •
