Public Huawei document I linked couple days ago mentioned factory diagnostics tool called " Huawei deviceLocker V0.1" that will grant access to root shell on router. I got curious on how this would actually work and came to conclusion it must be something extremely simple and insecure, it IS Huawei after all. Did some poking around /bin/web process I figured this out - it's all there in clear-text for anyone to read. And that admin password is in Huawei docs, not exactly secret either. In case you didn't realize there's no need for authentication to exploit this. Protip: Try to hide you backdoors a bit better next time.
