CVE-2017-12226
HighSummary
A vulnerability in the web-based Wireless Controller GUI of Cisco IOS XE Software allows an authenticated, remote attacker to elevate their privileges on an affected device. The issue is due to incomplete input validation of HTTP requests by the affected GUI, potentially leading to privilege escalation.
Risk Assessment
An attacker exploiting this vulnerability could gain full control over the device, posing a significant security risk to the organization's network.
Recommendation
It is recommended to update the software to the latest version to mitigate this vulnerability and to monitor access to the Wireless Controller GUI.

Original NVD description (English source)
A vulnerability in the web-based Wireless Controller GUI of Cisco IOS XE Software for Cisco 5760 Wireless LAN Controllers, Cisco Catalyst 4500E Supervisor Engine 8-E (Wireless) Switches, and Cisco New Generation Wireless Controllers (NGWC) 3850 could allow an authenticated, remote attacker to elevate their privileges on an affected device. The vulnerability is due to incomplete input validation of HTTP requests by the affected GUI, if the GUI connection state or protocol changes. An attacker could exploit this vulnerability by authenticating to the Wireless Controller GUI as a Lobby Administrator user of an affected device and subsequently changing the state or protocol for their connection to the GUI. A successful exploit could allow the attacker to elevate their privilege level to administrator and gain full control of the affected device. This vulnerability affects the following Cisco products if they are running Cisco IOS XE Software Release 3.7.0E, 3.7.1E, 3.7.2E, 3.7.3E, 3.7.4E,
