Hi,

I found two vulnerabillities in PHP Counter 7.2

PHP Counter Vendor:
http://www.ekstreme.com/phplabs/phpcounter.php

First an XSS problem (file phpcounterxss.txt)
Second a Path disclosure vulnerabillity (file phpcounterdir.txt).

PHP Counter 7.2 does not filter "<>" tags in EpochPrefix
parameter. Cross site scripting and HTML injection is possible.

Exploitation:

http://www.yourwebsite.org/CounterDirectory/index.php?Plugin=All%20Hits&EpochPrefix=";></a></div><script>a=/XSS/%0aalert(a.source)</script>

The injected script is called multiple times.

XSS is hard to do because ' and " are filtered.

That's all :-)
