- Exploitation: none
- Automatable: yes
- Technical impact: total
Summary
The firmware update process for the basemodule of the charging controller only validates the CRC32 checksum without cryptographic signature verification. This allows an unauthenticated remote attacker to install a modified firmware, resulting in full system compromise.
