AnalysisAIv1 – Jul 21, 2026

Authentication bypass via hard-coded backdoor accounts in Autel MaxiCharger Single EV charging stations (firmware through V1.03.51) lets remote attackers gain administrative control of the web management interface. Two undocumented privileged accounts use a vendor-defined password derivation tied to device-specific values, so anyone who knows the algorithm and inputs can authenticate as admin without legitimate credentials. Publicly available exploit code exists (CyberDanube); no public evidence of active exploitation at time of analysis.

DescriptionCVE.org

Two undocumented privileged accounts exist in Autel Maxi Charger Single firmware through V1.03.51. The accounts use vendor-defined password derivation mechanisms based on device-specific values, allowing an attacker with knowledge of the algorithm and required inputs to authenticate to the web management interface with administrative privileges.

Executive ViewAI

Why It Matters

Autel MaxiCharger Single EV charging stations (firmware V1.03.51 and earlier) contain hard-coded backdoor accounts enabling remote attackers to gain full administrative control of the web management interface via authentication bypass. With publicly available exploit code and no vendor patch available, this directly threatens operational continuity and safety of organizations' EV charging infrastructure.

Recommended Action

Within 24 hours: No vendor-released patch currently exists; inventory all Autel MaxiCharger Single units and firmware versions in production, then immediately restrict network access to affected stations to trusted administrative networks only. Within 7 days: Implement network segmentation isolating charging station management interfaces, enforce access controls requiring VPN or fixed-IP administrative authentication, and enable comprehensive logging of all administrative access attempts. Within 30 days: Monitor Autel security advisories for vendor patches; if none available, develop a replacement strategy or pursue emergency firmware updates from Autel (contact support immediately for remediation options).

Business Impact: Severe
Compensating Controls

Until vendor patch available: isolate station management interfaces to trusted administrative network only with firewall rules blocking all external access; disable or restrict public internet routing to charging station web interfaces; implement 24/7 monitoring and alerting on all administrative access attempts with immediate incident response procedures; deploy intrusion detection targeting CVE-2026-8982 exploit signatures; contact Autel technical support immediately to determine whether emergency firmware releases or additional compensating controls are available.
