I. Description PHP is a scripting language that is designed for web-based applications and can be imbedded directly into HTML. PHP versions prior to 5.2.6 contain a path translation vulnerability. For more information about this issue, see the PHP CVS log. II. Impact An attacker may be able to execute arbitrary code in the context of an application that uses the vulnerable function.
