DescriptionCVE.org

Leftover debug modules contain fixed credentials for internal AWS Cognito test sandboxes, risking asset exploitation.

AnalysisAI

Hard-coded AWS Cognito credentials embedded in leftover debug modules of the Acer Connect M6E 5G Portable WiFi Router expose internal cloud test sandbox environments to remote unauthenticated attackers. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms no authentication, no network proximity, and no user interaction is required, meaning any attacker who obtains the static credentials - through firmware extraction or disclosure - can authenticate to Acer's AWS Cognito-backed test infrastructure. …

Vulnerability AssessmentAI

Exploitation The vulnerability is present in any Acer Connect M6E unit running firmware that includes the leftover debug modules - the CPE wildcard indicates all currently documented versions are affected. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 6.9 is driven by maximally favorable attacker conditions: network-accessible (AV:N), low complexity (AC:L), no authentication required (PR:N), and no user interaction (UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker downloads or physically extracts the Acer Connect M6E firmware image and reverse-engineers the debug module binaries to recover the embedded AWS Cognito credentials. Using a standard AWS SDK or CLI, the attacker authenticates directly to Acer's Cognito test sandbox environment and queries or modifies cloud resources accessible to that identity. …
Remediation Apply firmware updates for the Acer Connect M6E as directed by the Acer vendor advisory at https://community.acer.com/en/kb/articles/19707. … Detailed patch versions, workarounds, and compensating controls in full report.
