CVE-2022-20728 – Cisco Access Points VLAN Bypass from Native VLAN Vulnerability
https://notcve.org/view.php?id=CVE-2022-20728
A vulnerability in the client forwarding code of multiple Cisco Access Points (APs) could allow an unauthenticated, adjacent attacker to inject packets from the native VLAN to clients within nonnative VLANs on an affected device. This vulnerability is due to a logic error on the AP that forwards packets that are destined to a wireless client if they are received on the native VLAN. An attacker could exploit this vulnerability by obtaining access to the native VLAN and directing traffic directly to the client through their MAC/IP combination. A successful exploit could allow the attacker to bypass VLAN separation and potentially also bypass any Layer 3 protection mechanisms that are deployed. Una vulnerabilidad en el código de reenvío de clientes de varios Puntos de Acceso (AP) de Cisco podría permitir a un atacante adyacente no autenticado inyectar paquetes de la VLAN nativa a clientes dentro de VLANs no nativas en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-apvlan-TDTtb4FY • CWE-284: Improper Access Control •
CVE-2022-20695 – Cisco Wireless LAN Controller Management Interface Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-20695
A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to bypass authentication controls and log in to the device through the management interface This vulnerability is due to the improper implementation of the password validation algorithm. An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials. A successful exploit could allow the attacker to bypass authentication and log in to the device as an administrator. The attacker could obtain privileges that are the same level as an administrative user but it depends on the crafted credentials. Note: This vulnerability exists because of a non-default device configuration that must be present for it to be exploitable. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-auth-bypass-JRNhV4fF • CWE-287: Improper Authentication CWE-303: Incorrect Implementation of Authentication Algorithm •
CVE-2021-34740 – Cisco Aironet Access Points WLAN Control Protocol Packet Buffer Leak Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34740
A vulnerability in the WLAN Control Protocol (WCP) implementation for Cisco Aironet Access Point (AP) software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect error handling when an affected device receives an unexpected 802.11 frame. An attacker could exploit this vulnerability by sending certain 802.11 frames over the wireless network to an interface on an affected AP. A successful exploit could allow the attacker to cause a packet buffer leak. This could eventually result in buffer allocation failures, which would trigger a reload of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-airo-wpa-pktleak-dos-uSTyGrL • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2020-3261 – Cisco Mobility Express Software Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2020-3261
A vulnerability in the web-based management interface of Cisco Mobility Express Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user with an active session on an affected device to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions, including modifying the configuration, with the privilege level of the user. Una vulnerabilidad en la interfaz de administración basada en web del Software Cisco Mobility Express podría permitir a un atacante remoto no autenticado llevar a cabo un ataque de tipo cross-site request forgery (CSRF) sobre un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-mob-exp-csrf-b8tFec24 • CWE-352: Cross-Site Request Forgery (CSRF) •
CVE-2020-3260 – Cisco Aironet Series Access Points Client Packet Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3260
A vulnerability in Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to the improper processing of client packets that are sent to an affected access point (AP). An attacker could exploit this vulnerability by sending a large number of sustained client packets to the affected AP. A successful exploit could allow the attacker to cause the affected AP to crash, resulting in a DoS condition. Una vulnerabilidad en el Software Cisco Aironet Series Access Points podría permitir a un atacante no autenticado adyacente causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-airo-wpa-dos-5ZLs6ESz • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
