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: 20EXPL: 0CVE-2019-15265 – Cisco Aironet Access Points Bridge Protocol Data Unit Port Disable Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-15265
A vulnerability in the bridge protocol data unit (BPDU) forwarding functionality of Cisco Aironet Access Points (APs) could allow an unauthenticated, adjacent attacker to cause an AP port to go into an error disabled state. The vulnerability occurs because BPDUs received from specific wireless clients are forwarded incorrectly. An attacker could exploit this vulnerability on the wireless network by sending a steady stream of crafted BPDU frames. A successful exploit could allow the attacker to cause a limited denial of service (DoS) attack because an AP port could go offline. Una vulnerabilidad en la funcionalidad de reenvío de bridge protocol data unit (BPDU) de Cisco Aironet Access Points (APs), podría permitir a un atacante adyacente no autenticado causar que un puerto del AP entre en un estado de error deshabilitado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-airo-dos • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 24EXPL: 0CVE-2019-15264 – Cisco Aironet Access Points and Catalyst 9100 Access Points CAPWAP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-15264
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol implementation of Cisco Aironet and Catalyst 9100 Access Points (APs) could allow an unauthenticated, adjacent attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to improper resource management during CAPWAP message processing. An attacker could exploit this vulnerability by sending a high volume of legitimate wireless management frames within a short time to an affected device. A successful exploit could allow the attacker to cause a device to restart unexpectedly, resulting in a DoS condition for clients associated with the AP. Una vulnerabilidad en la implementación del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco Aironet and Catalyst 9100 Access Points (APs), podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se reinicie inesperadamente, resultando en una condición de denegación de servicio ( DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-airo-capwap-dos • CWE-400: Uncontrolled Resource Consumption •
