Configuration error in Cisco Mobility Express - CVE-2018-0226
Published: May 7, 2018
Cisco Mobility Express
Detailed vulnerability description
The vulnerability allows a remote authenticated attacker to gain elevated privileges on the target system.
The weakness exists due to the Cisco Mobility Express controller configures the default SSH user account for an access point to be the first SSH user account that was created for the Mobility Express controller, if an administrator added user accounts directly to the controller instead of using the default configuration or the SSH username creation wizard. Although the user account has read-only privileges for the Mobility Express controller, the account can have administrative privileges for an associated access point. A remote attacker who has valid user credentials for an affected controller can use the default SSH user account to authenticate via SSH, log in with administrative privileges and perform arbitrary administrative actions.
