Detailsinfo

A vulnerability has been found in Cisco Aironet (Wireless LAN Software) (affected version not known) and classified as problematic. Affected by this vulnerability is some unknown functionality of the component QoS. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. The summary by CVE is:

A vulnerability in the quality of service (QoS) feature of Cisco Aironet Series Access Points (APs) could allow an authenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation on QoS fields within Wi-Fi frames by the affected device. An attacker could exploit this vulnerability by sending malformed Wi-Fi frames to an affected device. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a DoS condition.

The bug was discovered 04/17/2019. The weakness was disclosed 04/18/2019 (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is known as CVE-2019-1826 since 12/06/2018. The attack can only be initiated within the local network. A single authentication is required for exploitation.
