I wonder how many of the affected routers have their remote management interfaces turned on by default - if they are off (as they should be) then it probably isn't that big a deal... I mean, loads of routers have admin:admin set and left unchanged
That doesn't actually mitigate the problem much, if at all. Many of these devices are likely to be vulnerable to CSRF; a malicious web page may be able to trigger requests which log into a local router and perform management tasks.
