A CRLF cross-site scripting vulnerability has been identified in certain configurations of the SiteMinder Web Agent for IIS Web Server and SiteMinder Web Agent for Domino Web Server. As a result, an attacker can execute arbitrary Javascript code in a client browser.
The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.
