Hi,


If you have CCO account you can check your IOS vulnerabilities/bugs from the Bug Toolkit http://tools.cisco.com/Support/BugToolKit/


With or without vulnerabilities, without securing the IOS, your router can be accessed by unauthorized people or they can send DDOS top bring it down. To minimize/eliminate exposure to external threats especially if your router is an internet router, check the guidelines in these links;

Check your router exposure to external threats by using Nessus the #1 vulnerability scanner (voted by both good and bad hackers).

For bugs, you can avoid it by not using the IOS feature that are affected by bugs if you don't need it. Best is to have a back to back maintenance for IOS update.
