Technical details
The firmware for the Acer Connect M6E 5G router (version M6E_AI_1.00.000019 and earlier) contains hard-coded credentials (CWE-798) within leftover debug modules. These credentials provide access to internal AWS Cognito test sandboxes used during development. An unauthenticated attacker with network access to the firmware or device components can extract these fixed credentials to gain unauthorized access to the associated cloud testing environments. Acer has advised that a firmware update is being developed to expunge these testing/backdoor opcodes and transition to dynamic credential management.
