Autel Maxi Charger Single vulnerabilities

Autel Maxi Charger Single firmware through V1.03.51 is vulnerable to OS command injection when processing OCPP GetDiagnostics requests. A malicious or compromised OCPP server can supply a crafted diagnostics URL that results in arbitrary command execution on the charging station.

Autel Maxi Charger Single firmware up to version V1.03.51 is vulnerable to OS command injection via the /test endpoint on TCP port 9002. An unauthenticated attacker can supply crafted input in the url parameter to execute arbitrary system commands.

Autel Maxi Charger Single firmware up to version V1.03.51 allows unrestricted access to NXP i.MX6 recovery mode via exposed hardware pins. An attacker with physical access can boot arbitrary code in memory and modify or extract firmware and other sensitive data.

In Autel Maxi Charger Single firmware through V1.03.51, an accessible UART interface allows interruption of the boot process and access to the U-Boot bootloader. An attacker with physical access can modify boot configuration or file system to gain OS access.

Autel Maxi Charger Single firmware through V1.03.51 contains a heap-based buffer overflow in the set_ap_param command handled by the /localcfg endpoint. An authenticated attacker can supply oversized input, resulting in denial of service and potentially arbitrary code execution.

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.
