SAP BusinessObjects Business Intelligence Platform (Administration Console), versions 4.2, 4.3, module BILogon/appService.jsp is reflecting requested parameter errMsg into response content without sanitation. This could be used by an attacker to build a special url that execute custom JavaScript code when the url is accessed.

The Fiori Launchpad of SAP BusinessObjects, before versions 4.2 and 4.3, does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.
