php-nusoap: XSS vulnerability due improper escaping of URLs

Cross-site scripting (XSS) vulnerability in NuSOAP 0.9.5, as used in MantisBT and other products, allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to an arbitrary PHP script that uses NuSOAP classes.

NuSOAP 0.9.5 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by nuSOAP/classes/class.wsdl.php and certain other files.
