DescriptionCVE.org

The hard-coded APK resource files never expire, and the shared scepter leads to information leaks and potential misuse.

AnalysisAI

Information disclosure in the Acer Connect M6E 5G Portable WiFi Router (firmware versions up to and including M6E_AI_1.00.000019) stems from hard-coded, non-expiring credentials embedded in the companion APK that are shared across all deployments. Remote attackers can extract these static secrets from any copy of the application and use them to access sensitive router data without authentication, and no public exploit identified at time of analysis.

Vulnerability AssessmentAI

Exploitation Exploitation requires that the Acer Connect M6E 5G Portable WiFi Router be running firmware at or below M6E_AI_1.00.000019 with its companion Android APK in use, and that the API endpoints or device interfaces which trust the hard-coded shared secret be reachable by the attacker (network attack vector per CVSS AV:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS v4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H) yields 8.7 - network-reachable, low complexity, no privileges or user interaction, and high confidentiality impact with no integrity or availability effect, which matches a credential/data-disclosure flaw rather than an RCE. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker downloads the Acer Connect companion APK from a public mirror, decompiles it with jadx, and extracts the hard-coded 'scepter' token from its resource files. Because the same token is embedded in every distribution, the attacker can then issue authenticated-looking API calls to any internet-reachable M6E device or backend service that trusts the shared secret, harvesting subscriber/device data at scale without ever touching the victim's network directly.
Remediation Patch status is unclear from the provided data - Acer's community advisory at https://community.acer.com/en/kb/articles/19707 should be consulted for the fixed firmware and APK build; no vendor-released patch version was independently confirmed in the supplied intelligence. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

24 hours: Inventory all Acer Connect M6E 5G routers (firmware M6E_AI_1.00.000019 and earlier); document current configuration and isolation status; restrict network access to management interfaces. …
