Vulnerability from fkie_nvd - Published: 2018-10-05 14:29 - Updated: 2024-11-21 03:38
Severity ?
6.1 (Medium) - CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H
Summary
A vulnerability in the errdisable per VLAN feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause the device to crash, leading to a denial of service (DoS) condition. The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition.
