No worries. Siemens backdoors are even worse.

Indeed. Siemens vulnerabilities is precisely how Stuxnet worked.

I would love to know if this was ever disclosed to Siemens, especially prior to the purchase.

In any case, someone is RuggedCom should be fired for doing nothing about this. My impression after reading the Seclist notice is that they were playing a waiting game.

Oh good, then at least next time when Siemens develops and helps deploy more Internet censoring infrastructure for oppressive regimes again, there'll be some backdoors in it!
