Cross site scripting

SAP Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability. This attack can be used to non-permanently deface or modify portal content. The execution of script content by a victim registered on the portal could compromise the confidentiality and integrity of victim?s web browser session.
