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.

AnalysisAI

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.
