Description
IBM Verify Identity Access Container 11.0 through 11.0.2 and IBM Security Verify Access Container 10.0 through 10.0.9.1 and IBM Verify Identity Access 11.0 through 11.0.2 and IBM Security Verify Access 10.0 through 10.0.9.1 allows certificate listings retrieved via a browser session to return a JSON payload while incorrectly specifying the response Content-Type as text/html. Because the content is delivered with an HTML MIME type, browsers may interpret the JSON data as executable script under certain conditions. This creates an opportunity for JavaScript injection, potentially leading to cross-site scripting (XSS).
