Valentin Höbel has discovered some vulnerabilities in dl_stats, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "id" parameter in view_file.php and download.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "id" parameter in download_proc.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities are confirmed in version 2.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
