What is CVE-2009-20006?

The administrative file manager in osCommerce versions up to 2.2 RC2a is susceptible to an arbitrary file upload vulnerability. This flaw exists due to inadequate input validation and improper access control within the file management interface (admin/file_manager.php). An unauthenticated attacker can exploit this vulnerability by sending a crafted POST request to upload a malicious PHP file. Once uploaded, this file can be executed on the server, enabling the attacker to run arbitrary code and compromise the system.

Affected Version(s)

osCommerce * <= 2.2 RC2a
