Description

A vulnerability in the lobby ambassador web interface of Cisco IOS XE Wireless Controller Software could allow an authenticated, remote attacker to remove arbitrary users that are defined on an affected device.

This vulnerability is due to insufficient access control of actions executed by lobby ambassador users. An attacker could exploit this vulnerability by logging in to an affected device with a lobby ambassador user account and sending crafted HTTP requests to the API. A successful exploit could allow the attacker to delete arbitrary user accounts on the device, including users with administrative privileges.

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
