AI-suggested
Since the vulnerability involves static cryptographic keys, mitigation would typically require a firmware update that replaces static keys with unique per-device keys and enforces secure boot with digitally signed firmware. Until a fix is available, restrict physical and network access to affected devices to prevent key extraction and unauthorized firmware installation.
Description
Arista C-260 and C-250 access points contain a vulnerability due to the use of fleet-wide static cryptographic keys for firmware image verification and SSLP authentication. This allows an attacker with access to these keys to create modified firmware that can bypass verification checks. Other Arista access point models are not affected as they use digitally signed upgrade images with secure boot.
