Name of the Vulnerable Software and Affected Versions:
Cisco Aironet 1800 Series Access Points versions 8.2.121.0 through 8.5.105.0
Cisco Aironet 2800 Series Access Points versions 8.3.102.0 through 8.5.105.0
Cisco Aironet 3800 Series Access Points versions 8.3.102.0 through 8.5.105.0
Description:
A vulnerability in the assignment and management of default user accounts for Secure Shell (SSH) access could allow an authenticated, remote attacker to gain elevated privileges on an affected access point. The vulnerability exists because 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. 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.
Recommendations:
For Cisco Aironet 1800 Series Access Points versions 8.2.121.0 through 8.5.105.0, update the software to a version outside of this range to resolve the issue.
For Cisco Aironet 2800 Series Access Points versions 8.3.102.0 through 8.5.105.0, update the software to a version outside of this range to resolve the issue.
For Cisco Aironet 3800 Series Access Points versions 8.3.102.0 through 8.5.105.0, update the software to a version outside of this range to resolve the issue.
As a temporary workaround, consider restricting access to the default SSH user account to minimize the risk of exploitation.
