Technical details
The vulnerability stems from incorrect permission assignments (CWE-732) within a core Broadcast Receiver component of the Acer Connect M6E router. Specifically, the receiver lacks proper access controls (exported=true without signature-level permissions), allowing unauthorized local applications to trigger administrative operations. An attacker can exploit this by sending a crafted broadcast event to rewrite the default Mobile Device Management (MDM) endpoint address. This shifts administrative ownership to an external attacker-controlled server, enabling full device compromise. Acer is addressing this by restricting the receiver's visibility and enforcing signature-level authorization.
