This can be exploited to upload and execute arbitrary PHP code e.g. via ".phtml" files. 2) Input passed e.g. via the "lang_crm" parameter to phprint.php or the "current_language" parameter to graph.php is not properly verified in the "return_application_language()" function in include/utils/utils.php before being used to include files. This can be exploited to include arbitrary file from local resources via directory traversal sequences and URL-encoded NULL bytes. Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled. 3) Input passed via the "user_name" and "user_password" parameters to index.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. 4) Input passed via the "label" parameter to index.php (when "module" is set to "Settings" and "action" is set to "GetFieldInfo") 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 5.2.0. Other versions may also be affected. SOLUTION: Update to version 5.2.1.
