Cross Site Scripting (XSS) vulnerability in the To OLAP (XMLA) component Under the Connect menu in Flexmonster Pivot Table & Charts 2.7.17.
Reflected XSS:
The Reflected XSS is a result of insufficient input sanitization of the 'path' parameter when fetching the file specifications (file_specs.php). Below I have provided an example URL. When using this URL the user navigates to an non-existing file (the XSS payload). This results in the execution of the payload.
