Exploit #1 will be made public. Cisco will released fixed code. Good service providers will upgrade. The upgraded code version will be the one targeted by the second, unknown, exploit. A two-part worm can infect Windows boxen via any common method, and then use them to try the exploit against routers. A windows box can find routers to attack easily enough by doing traceroutes to various sites. Then, the windows boxen can try a limited set of exploit variants on each router. Not all routers will be affected, but some will. As for what the worm could do - well, it could report home to the worm creators that "Hey, you 0wn X number of routers", or it could do something fun like erasing configs and locking out console ports. ;-) Honestly, I've been expecting something like that to happen for years now. <shrug>
