CVSS v3.1 |
| Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords. |
| Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. |
| Cisco AP340 base station produces predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections. |
| Cisco 1200, 1131, and 1240 series Access Points, when operating in Lightweight Access Point Protocol (LWAPP) mode and controlled by 2000 and 4400 series Airespace WLAN controllers running 3.1.59.24, allow remote attackers to send unencrypted traffic to a secure network using frames with the MAC address of an authenticated end host. |
| Cisco IOS before 12.3-7-JA2 on Aironet Wireless Access Points (WAP) allows remote authenticated users to cause a denial of service (termination of packet passing or termination of client connections) by sending the management interface a large number of spoofed ARP packets, which creates a large ARP table that exhausts memory, aka Bug ID CSCsc16644. |
| Cisco 340-series Aironet access point using firmware 11.01 does not use 6 of the 24 available IV bits for WEP encryption, which makes it easier for remote attackers to mount brute force attacks. |
| Cisco Aironet 340 Series wireless bridge before 8.55 does not properly disable access to the web interface, which allows remote attackers to modify its configuration. |
| A vulnerability in the IPv6 Router Advertisement (RA) packet processing of Cisco Access Point Software could allow an unauthenticated, adjacent attacker to modify the IPv6 gateway on an affected device.
This vulnerability is due to a logic error in the processing of IPv6 RA packets that are received from wireless clients. An attacker could exploit this vulnerability by associating to a wireless network and sending a series of crafted IPv6 RA packets. A successful exploit could allow the attacker to temporarily change the IPv6 gateway of an affected device. This could also lead to intermittent packet loss for any wireless clients that are associated with the affected device. |
| A vulnerability in the Device Analytics action frame processing of Cisco Wireless Access Point (AP) Software could allow an unauthenticated, adjacent attacker to inject wireless 802.11 action frames with arbitrary information.
This vulnerability is due to insufficient verification checks of incoming 802.11 action frames. An attacker could exploit this vulnerability by sending 802.11 Device Analytics action frames with arbitrary parameters. A successful exploit could allow the attacker to inject Device Analytics action frames with arbitrary information, which could modify the Device Analytics data of valid wireless clients that are connected to the same wireless controller. |
| A vulnerability in the boot process of Cisco Access Point (AP) Software could allow an unauthenticated, physical attacker to bypass the Cisco Secure Boot functionality and load a software image that has been tampered with on an affected device.
This vulnerability exists because unnecessary commands are available during boot time at the physical console. An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised. |
| A vulnerability in the web-based management interface of Cisco Unified Industrial Wireless Software for Cisco Ultra-Reliable Wireless Backhaul (URWB) Access Points could allow an unauthenticated, remote attacker to perform command injection attacks with root privileges on the underlying operating system.
This vulnerability is due to improper validation of input to the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying operating system of the affected device. |
| 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. |
| 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. |
| 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. |
| A vulnerability in the handling of encrypted wireless frames of Cisco Aironet Access Point (AP) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on the affected device.
This vulnerability is due to incomplete cleanup of resources when dropping certain malformed frames. An attacker could exploit this vulnerability by connecting as a wireless client to an affected AP and sending specific malformed frames over the wireless connection. A successful exploit could allow the attacker to cause degradation of service to other clients, which could potentially lead to a complete DoS condition. |
| A vulnerability in the implementation of Protected Extensible Authentication Protocol (PEAP) functionality for standalone configurations of Cisco Aironet 1800, 2800, and 3800 Series Access Points could allow an unauthenticated, adjacent attacker to bypass authentication and connect to an affected device. The vulnerability exists because the affected device uses an incorrect default configuration setting of fail open when running in standalone mode. An attacker could exploit this vulnerability by attempting to connect to an affected device. A successful exploit could allow the attacker to bypass authentication and connect to the affected device. This vulnerability affects Cisco Aironet 1800, 2800, and 3800 Series Access Points that are running a vulnerable software release and use WLAN configuration settings that include FlexConnect local switching and central authentication with MAC filtering. Cisco Bug IDs: CSCvd46314. |
| A vulnerability in the handling of 802.11w Protected Management Frames (PAF) by Cisco Aironet 3800 Series Access Points could allow an unauthenticated, adjacent attacker to terminate a valid user connection to an affected device, aka Denial of Service. The vulnerability exists because the affected device does not properly validate 802.11w PAF disassociation and deauthentication frames that it receives. An attacker could exploit this vulnerability by sending a spoofed 802.11w PAF frame from a valid, authenticated client on an adjacent network to an affected device. A successful exploit could allow the attacker to terminate a single valid user connection to the affected device. This vulnerability affects Access Points that are configured to run in FlexConnect mode. Cisco Bug IDs: CSCvc20627. |
| A vulnerability in the packet processing code of Cisco IOS Software for Cisco Aironet Access Points could allow an unauthenticated, adjacent attacker to retrieve content from memory on an affected device, which could lead to the disclosure of confidential information. The vulnerability is due to insufficient condition checks that are performed by the affected device when the device adds padding to egress packets. An attacker could exploit this vulnerability by sending a crafted IP packet to an affected device. A successful exploit could allow the attacker to retrieve content from memory on the affected device, which could lead to the disclosure of confidential information. Cisco Bug IDs: CSCvc21581. |
| A vulnerability in Extensible Authentication Protocol (EAP) ingress frame processing for the Cisco Aironet 1560, 2800, and 3800 Series Access Points could allow an unauthenticated, Layer 2 radio frequency (RF) adjacent attacker to cause the Access Point (AP) to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of the EAP frame. An attacker could exploit this vulnerability by sending a malformed EAP frame to the targeted device. A successful exploit could allow the attacker to cause the AP to reload, resulting in a DoS condition while the AP is reloading. It may be necessary to manually power cycle the device in order for it to recover. This vulnerability affects the following Cisco products running either the Lightweight AP Software or Mobility Express image: Aironet 1560 Series Access Points, Aironet 2800 Series Access Points, Aironet 3800 Series Access Points. Note: The Cisco Aironet 1560 Series Access Point device is supported as of release 8.3.112.0. Cisco Bug IDs: CSCve18935. |
| A Denial of Service Vulnerability in 802.11 ingress connection authentication handling for the Cisco Mobility Express 2800 and 3800 Access Points (APs) could allow an unauthenticated, adjacent attacker to cause authentication to fail. Affected Products: This vulnerability affects Cisco Mobility Express 2800 Series and 3800 Series Access Points when configured in local mode in 40 MHz. More Information: CSCvb33575. Known Affected Releases: 8.2(121.12) 8.4(1.82). Known Fixed Releases: 8.2(131.2) 8.2(131.3) 8.2(131.4) 8.2(141.0) 8.3(104.53) 8.3(104.54) 8.4(1.80) 8.4(1.85). |
