As the International PHP Maagzine reports today there's been a file inclusion vulnerability found (from Secunia) in the DreamStats package:
Secunia's latest advisory points out a vulnerability in DreamStats, which could be exploited by remote attackers to execute arbitrary commands. This issue is due to an input validation error in the "index.php" script that does not validate the "rootpath" parameter, which could be exploited by remote attackers to include malicious PHP scripts and execute arbitrary commands with the privileges of the web server.
Those at risk are systems running versions 4.2 and prior and should update immediately. DreamStats is a package for displaying the statistics for Call of Duty related games on a website.
