CVSS: 6.7EPSS: 0%CPEs: 17EXPL: 0CVE-2021-1449 – Cisco Access Point Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1449
A vulnerability in the boot logic of Cisco Access Points Software could allow an authenticated, local attacker to execute unsigned code at boot time. The vulnerability is due to an improper check that is performed by the area of code that manages system startup processes. An attacker could exploit this vulnerability by modifying a specific file that is stored on the system, which would allow the attacker to bypass existing protections. A successful exploit could allow the attacker to execute unsigned code at boot time and bypass the software image verification check part of the secure boot process of an affected device. Note: To exploit this vulnerability, the attacker would need to have access to the development shell (devshell) on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-privesc-wEVfp8Ud • CWE-284: Improper Access Control •
CVSS: 7.4EPSS: 0%CPEs: 13EXPL: 0CVE-2021-1439 – Cisco Aironet Access Points FlexConnect Multicast DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1439
A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of incoming mDNS traffic. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device through a wireless network that is configured in FlexConnect local switching mode or through a wired network on a configured mDNS VLAN. A successful exploit could allow the attacker to cause the access point (AP) to reboot, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad multicast DNS (mDNS) gateway del Software Cisco Aironet Series Access Points, 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-aironet-mdns-dos-E6KwYuMx • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 0CVE-2021-1437 – Cisco Aironet Access Points FlexConnect Upgrade Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1437
A vulnerability in the FlexConnect Upgrade feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, remote attacker to obtain confidential information from an affected device. This vulnerability is due to an unrestricted Trivial File Transfer Protocol (TFTP) configuration. An attacker could exploit this vulnerability by sending a specific TFTP request to an affected device. A successful exploit could allow the attacker to download any file from the filesystem of the affected access point (AP). Una vulnerabilidad en la funcionalidad FlexConnect Upgrade del Software Cisco Aironet Series Access Points, podría permitir a un atacante remoto no autenticado obtenga información confidencial de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-info-disc-BfWqghj • CWE-275: Permission Issues •
CVSS: 7.4EPSS: 0%CPEs: 30EXPL: 0CVE-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 •
CVSS: 8.6EPSS: 0%CPEs: 58EXPL: 0CVE-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 •
