CVE-2024-5684

Unauthenticated web access via unsigned JWT acceptance

Published Jun 6, 2024 · Updated Aug 1, 2024

Authentication bypass in ID. Charger Connect and Pro SPR3.2B, SPR3.51, and SPR3.52 allows remote attackers to access the web interface. The JWT library accepts attacker-supplied tokens that declare the none algorithm without verifying a signature, treating them as authenticated sessions. Access requires the charger's private network or Ethernet interface and grants ordinary-user configuration functions, including interface changes, factory reset, Wi-Fi SSID enumeration, and system-information access, but not developer or administrator rights.
