Technical details
The vulnerability is a case of sensitive information disclosure (CWE-200) resulting from misconfigured AWS S3 buckets. Specifically, the cloud storage containers used to store active telemetry data from Acer Connect M6E 5G routers were set with overly permissive access controls, lacking the 'Block Public Access' setting. This allows unauthenticated remote actors to read telemetry logs directly over the network. Acer has recommended remediating this by enabling S3 Block Public Access and implementing restrictive bucket policies based on the principle of least privilege.
