Technical Description
A vulnerability in the boot logic of Cisco Access Points Software could allow an authenticated, local attacker to execute unsigned code at boot time. The vulnerability is due to an improper check that is performed by the area of code that manages system startup processes. An attacker could exploit this vulnerability by modifying a specific file that is stored on the system, which would allow the attacker to bypass existing protections. A successful exploit could allow the attacker to execute unsigned code at boot time and bypass the software image verification check part of the secure boot process of an affected device. Note: To exploit this vulnerability, the attacker would need to have access to the development shell (devshell) on the device.
Remediation
Check the references section for vendor advisories and patches from cisco. Update aironet_access_point_software to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
