PHP Running Management 1.0.2 - 'index.php' Cross-Site Scripting

source: https://www.securityfocus.com/bid/27268/info

PHP Running Management is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

This issue affects versions prior to PHP Running Management 1.0.3.
