CVE-2020-3260 (GCVE-0-2020-3260)

Vulnerability from cvelistv5 – Published: 2020-04-15 20:11 – Updated: 2024-11-15 17:29

Title

Cisco Aironet Series Access Points Client Packet Processing Denial of Service Vulnerability

Summary

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.
