Technical details
The AcerConnect OTA application contains hard-coded AES-128-CBC cryptographic keys (CWE-321). Because these keys are static across the product line, a remote attacker can use them to generate valid authorization credentials for any arbitrary IMEI number. This bypasses intended access controls, allowing the attacker to query the update catalog and retrieve protected firmware binaries via pre-signed cloud links. Acer is addressing this by transitioning to dynamic, per-device credential issuance.
