Well, here's an oldie but goodie, which we first saw at least 3 years
ago. Lo and behold, it's apparently STILL broken. Sorry, no vendor
notification - we told them 3 years ago. ;)
FlexLM 'lmdown' command will chow your license server from anywhere on
the Internet - all you need is a copy of the license file. The
authentication appears to be "Well, you appear to be root on the
machine that you typed 'lmdown' on".
In fact, you don't even need the license file. At least on "(lmgrd)
FLEXlm (v6.0d)", all you needed was your own file that had 'SERVER
hostname bozo-number port'. Changing bozo-number didn't affect the
ability to shut down the server. All you probably need to do is
figure out the packet format, and launch one. ;)
Any skriptz kiddies looking to write a DOS, here's your chance. ;)
