The vulnerability exists because the Cisco Mobility Express controller of the affected software 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 could have administrative privileges for an associated access point. An attacker who has valid user credentials for an affected controller could exploit this vulnerability by using the default SSH user account to authenticate to an affected access point via SSH. A successful exploit could allow the attacker to log in to the affected access point with administrative privileges and perform arbitrary administrative actions. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
