CVSS: 7.8EPSS: 0%CPEs: 95EXPL: 0CVE-2021-1419 – Cisco Access Points SSH Management Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1419
A vulnerability in the SSH management feature of multiple Cisco Access Points (APs) platforms could allow a local, authenticated user to modify files on the affected device and possibly gain escalated privileges. The vulnerability is due to improper checking on file operations within the SSH management interface. A network administrator user could exploit this vulnerability by accessing an affected device through SSH management to make a configuration change. A successful exploit could allow the attacker to gain privileges equivalent to the root user. Una vulnerabilidad en la función de administración SSH de varias plataformas Cisco Access Points (APs), podría permitir a un usuario local autenticado modificar archivos en el dispositivo afectado y posiblemente alcanzar privilegios escalados. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cisco-ap-LLjsGxv • CWE-284: Improper Access Control •
CVSS: 8.6EPSS: 0%CPEs: 63EXPL: 0CVE-2021-1565 – Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2021-1565
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition. Varias vulnerabilidades en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9000 Family Wireless Controllers podrían permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-capwap-dos-gmNjdKOY • CWE-415: Double Free •
CVSS: 4.4EPSS: 0%CPEs: 16EXPL: 0CVE-2021-1423 – Cisco Aironet Access Points Arbitrary File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2021-1423
A vulnerability in the implementation of a CLI command in Cisco Aironet Access Points (AP) could allow an authenticated, local attacker to overwrite files in the flash memory of the device. This vulnerability is due to insufficient input validation for a specific command. An attacker could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to overwrite or create files with data that is already present in other files that are hosted on the affected device. Una vulnerabilidad en la implementación de un comando de CLI en Cisco Aironet Access Points (AP), podría permitir a un atacante local autenticado sobrescribir archivos en la memoria flash del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-foverwrt-HyVXvrtb • CWE-668: Exposure of Resource to Wrong Sphere •
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') •
