CVE-2020-24588 | 8 Arista, Cisco, Debian and 5 more | 350 C-100, C-100 Firmware, C-110 and 347 more | 2023-03-03 | 2.9 LOW | 3.5 LOW |
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. | |||||
CVE-2022-20855 | 1 Cisco | 30 Catalyst 9105, Catalyst 9105axi, Catalyst 9105axw and 27 more | 2022-10-27 | N/A | 6.7 MEDIUM |
A vulnerability in the self-healing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst Access Points could allow an authenticated, local attacker to escape the restricted controller shell and execute arbitrary commands on the underlying operating system of the access point. This vulnerability is due to improper checks throughout the restart of certain system processes. An attacker could exploit this vulnerability by logging on to an affected device and executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root. To successfully exploit this vulnerability, an attacker would need valid credentials for a privilege level 15 user of the wireless controller. | |||||
CVE-2022-20919 | 1 Cisco | 305 Asr-920-10sz-pd, Asr-920-12cz-a, Asr-920-12cz-d and 302 more | 2022-10-27 | N/A | 7.5 HIGH |
A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition. | |||||
CVE-2020-26139 | 5 Arista, Cisco, Debian and 2 more | 330 C-100, C-100 Firmware, C-110 and 327 more | 2022-09-29 | 2.9 LOW | 5.3 MEDIUM |
An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. | |||||
CVE-2020-26140 | 5 Alfa, Arista, Cisco and 2 more | 388 Awus036h, Awus036h Firmware, C-100 and 385 more | 2022-09-02 | 3.3 LOW | 6.5 MEDIUM |
An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration. | |||||
CVE-2020-24587 | 6 Arista, Cisco, Debian and 3 more | 332 C-100, C-100 Firmware, C-110 and 329 more | 2022-07-12 | 1.8 LOW | 2.6 LOW |
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. | |||||
CVE-2021-1615 | 1 Cisco | 7 Catalyst 9105, Catalyst 9115, Catalyst 9117 and 4 more | 2022-07-08 | 5.0 MEDIUM | 8.6 HIGH |
A vulnerability in the packet processing functionality of Cisco Embedded Wireless Controller (EWC) Software for Catalyst Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected AP. This vulnerability is due to insufficient buffer allocation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to exhaust available resources and cause a DoS condition on an affected AP, as well as a DoS condition for client traffic traversing the AP. | |||||
CVE-2020-3486 | 1 Cisco | 11 Catalyst 9105, Catalyst 9115, Catalyst 9117 and 8 more | 2021-10-19 | 6.1 MEDIUM | 6.5 MEDIUM |
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition of an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit these 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 on the affected device. | |||||
CVE-2021-34740 | 1 Cisco | 71 6300 Series Access Points, Aironet 1540, Aironet 1542d and 68 more | 2021-10-14 | 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-2020-3560 | 1 Cisco | 49 1111-4pwe, 1111-8plteeawb, 1111-8pwb and 46 more | 2021-04-16 | 7.8 HIGH | 8.6 HIGH |
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. |
