A whole pile of new vulnerabilities including remote code exploit were
revealed against specific models about 3 weeks ago; I had not heard of any
exploits, but, ...

Which is why the models and IOS versions would be very useful.

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.
