NVD description

When connecting to the Solax Cloud MQTT server the username is the "registration number", which is the 10 character string printed on the SolaX Power Pocket device / the QR code on the device. The password is derived from the "registration number" using a proprietary XOR/transposition algorithm. Attackers with the knowledge of the registration numbers can connect to the MQTT server and impersonate the dongle / inverters.

There was a notable authentication bypass and certificate validation failure impacting SolaX Cloud MQTT devices (CVE-2025-15573, CVE-2025-15574) recently that might be fun to explore. Iran also recently put a lot of money into Solar stuff with a 200 MW plant in Yazd and a 500 MW hybrid solar-hydro plant at Karkheh River. It's likely affected and been hard for them to get out there to patch for it.. 🤔
