Security Note Encoding fix for technical hidden fields, SAP security note 1340457

Description

Some web browsers that are unsupported by the SAP Web UI (such as IBM AppScan) sometimes make it possible to decode complex strings and to execute JavaScript code found in them for one’s own user by passing them in some request parameters (using special functionality provided by those unsupported browsers). This JavaScript code cannot be executed in another user’s session or in another session belonging to the same user, nor can it be executed by standard popular Browsers. It can only be executed for one’s own user, in the current session, in special browsers. Because of the complexity of the prerequisites, we are currently not aware of any working attack vector, thus exploitability is very unlikely.
