A vulnerability in the web-based management interface of the Wireless LAN Controller feature of Cisco IOS XE Software could allow an authenticated, remote attacker with a lobby ambassador user account to perform a command injection attack against an affected device.

 This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary Cisco IOS XE Software CLI commands with privilege level 15.

 Note: This vulnerability is exploitable only if the attacker obtains the credentials for a lobby ambassador account. This account is not configured by default.
