SAS Web Report Studio 4.4 allows XSS. /SASWebReportStudio/logonAndRender.do has two parameters: saspfsrequestbacklabellist and saspfsrequestbackurllist. The first one affects the content of the button placed in the top left. The second affects the page to which the user is directed after pressing the button, e.g., a malicious web page. In addition, the second parameter executes JavaScript, which means XSS is possible by adding a javascript: URL.
