Have you checked?  If the routers had vty access open (ssh or telnet) and
the passwords were easy to guess, then it's more likely that this was a
password compromise.  You can test this out by getting a copy of one of the
configs and decrypting the access password.  Or by asking your customers
whether their passwords were dictionary or simple words.

It's possible that there was a remotely accessible vulnerability, but ios
isn't known for this.
