cph2_echarge_firmware: Insufficient Verification of Data Authenticity
CVE-2024-11666 is a critical-severity insufficient verification of data authenticity vulnerability in cph2_echarge_firmware from Hardy-barth, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected cph2_echarge_firmware versions: 2.0.4 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of cph2_echarge_firmware you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Affected devices beacon to eCharge cloud infrastructure asking if there are any command they should run. This communication is established over an insecure channel since peer verification is disabled everywhere. Therefore, remote unauthenticated users suitably positioned on the network between an EV charger controller and eCharge infrastructure can execute arbitrary commands with elevated privileges on affected devices. This issue affects cph2_echarge_firmware: through 2.0.4.

The underlying weakness: Insufficient Verification of Data Authenticity
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
