SAP security note 1494889, "Unauthorized modification of displayed content T_SAM_DEMO". Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
The BSP-Application: T_SAM_DEMO, BSP-Page: CONSUMER.HTM could be abused by a malicious user, who could modify displayed application content without authorization and potentially obtain authentication information from other legitimate users.
Solution
The page is not a productive application and has been removed.
Reason and prerequisites
The BSP-Application: T_SAM_DEMO, BSP-Page: CONSUMER.HTM do not sufficiently encode OUTPUT parameters, resulting in a reflected cross-site scripting issue. A reflected cross-site scripting attack can be used to non-permanently deface or modify displayed content from a website.
Reflected cross-site scripting can be used to steal another user’s authentication information, such as data relating to their current session. An attacker who gains access to this data could use it to impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, the application’s security could be fully compromised.
