Add Eventlog Analzyer exploit

This is yet another exploit for a ManageEngine product, Eventlog Analyzer. h0ng10 had discovered this more than a year ago, but ManageEngine failed to resolve it so he made the discovery public yesterday evening. 
Long story short, I found the same bug a couple of months, and had an exploit ready for when ManageEngine fixed it. Since it's public now, I'm releasing the exploit. h0ng10 is credit properly as the original vulnerability discoverer.
This exploit has been very well tested in many Windows and Linux versions of the product, all the way from 7.0 to the latest 9.9 build 9002.
