CVE-2022-20728 1 Cisco 52 Aironet 1542d, Aironet 1542d Firmware, Aironet 1542i and 49 more 2024-02-28 N/A 4.7 MEDIUM
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.
CVE-2021-34740 1 Cisco 71 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router, 1100-8p Integrated Services Router and 68 more 2024-02-28 6.1 MEDIUM 7.4 HIGH
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.
CVE-2020-3552 1 Cisco 28 Access Points, Aironet 1542d, Aironet 1542i and 25 more 2024-02-28 6.1 MEDIUM 7.4 HIGH
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.
CVE-2020-3260 1 Cisco 12 Aironet 1542d, Aironet 1542d Firmware, Aironet 1542i and 9 more 2024-02-28 3.3 LOW 6.5 MEDIUM
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.
CVE-2020-3261 1 Cisco 34 6300 Series Access Points, 6300 Series Access Points Firmware, Aironet 1542d and 31 more 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
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.
