Show the technical text from the sources

SAP NetWeaver Enterprise Portal allows an unauthenticated attacker to inject malicious scripts into a URL parameter. The scripts are reflected in the server response and executed in a user's browser when the crafted URL is visited, leading to theft of session information, manipulation of portal content, or user redirection. This results in a low impact on confidentiality and integrity. There is no impact on availability.
