DescriptionCVE.org

The system Binder boundary accepts unverified pass-through AT commands, giving local applications the power to read baseband files or disable cellular connectivity.

AnalysisAI

Local privilege abuse in the Acer Connect M6E 5G Portable WiFi Router lets installed applications smuggle raw AT commands across the Android system Binder boundary, where they are forwarded to the cellular baseband without verification. Up to and including firmware M6E_AI_1.00.000019, low-privileged local apps can read sensitive baseband files (IMSI, configuration blobs) and disable cellular connectivity, with no public exploit identified at time of analysis and no CISA KEV listing.

Vulnerability AssessmentAI

Exploitation Attacker must already be running code locally on the Acer Connect M6E 5G Portable WiFi Router (firmware ≤ M6E_AI_1.00.000019) as an unprivileged on-device application that can reach the system Binder service exposing the AT-command pass-through; no user interaction, no elevated permissions, and no special configuration toggle are required because the pass-through accepts unverified commands by default. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector AV:L/AC:L/AT:N/PR:L/UI:N with VC:H/VI:H/VA:H reflects a high-impact local issue: any installed app with low privileges (no special permission, no user prompt) can both exfiltrate sensitive baseband data and brick connectivity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A user side-loads or is tricked into installing a benign-looking utility on the M6E. With only low-level local privileges and no user interaction, the app opens the exposed Binder endpoint and issues crafted AT commands that read baseband filesystem entries (leaking IMSI/EFS data) and then send a CFUN=0 / detach sequence to drop cellular service, denying connectivity to every device tethered to the hotspot.
Remediation Patch availability is not explicitly stated as a fixed version in the supplied data - treat this as 'Patch available per vendor advisory' and apply the firmware update referenced in Acer's KB at https://community.acer.com/en/kb/articles/19707 as soon as a release succeeding M6E_AI_1.00.000019 is published, verifying the build string in the device admin UI after upgrade. … Detailed patch versions, workarounds, and compensating controls in full report.
