Summary
Bender Charge Controller Vulnerability - Unsecure Communication
Severity
High
Notes
Summary: Bender is publishing this advisory to inform customers about a security vulnerability in the Charge Controller product families. Bender has analyzed the weakness and determined that the electrical safety of the devices is not affected. Bender considers the weakness to be of high risk and it should be patched immediately.
Impact: Due to an unsecure default configuration HTTP is used instead of HTTPS for the web interface.
Mitigation: To use HTTPS on the web interface, enable it in the settings.
CVE-2025-41708

Due to an unsecure default configuration HTTP is used instead of HTTPS for the web interface. An unauthenticated attacker on the same network could exploit this to learn sensitive data during transmission.

7.4 (High)
