Now I see what you mean. I think you are confusing the vulnerability in
TorStatus with the fact that Tor Exit Nodes might modify the traffic
that passes through them.
This has nothing to do with the vulnerably in TorStatus and is a totally
different issue.
Mike's Tor Exit scanner runs a lot of tests and I think it is likely
that an exit node messing with the traffic (injecting code) is detected.
After detection the exit node messing with the traffic will likely get
the badexit flag.
