SAP Security Note
High priority
SAP security note 1656658, “Unauthorized modification of displayed content in Web Dynpro”, is a note released on 08.05.2012. Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
Design time for Web Dynpro ABAP can be abused by an attacker, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.
Solution
Restrict the developer permissions to as few users as possible, or implement the provided correction.
To implement the correction, apply the support package mentioned in this note at least or follow the correction instructions provided.
Reason and prerequisites
Pages under design within the Design time for Web Dynpro ABAP 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 Web site.
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 may use it to impersonate the user and access all information with the same rights as the target user.
If an administrator is impersonated, the security of the application may be fully compromised.
Affected components
- SAP_BASIS 702
- SAP_BASIS 710 to 711
- SAP_BASIS 731
