Unauthorized modification of content in WS_DESIGN_TOOL, SAP security note 1693219

SAP security note 1693219, "Unauthorized modification of content in WS_DESIGN_TOOL", is a note released on May 8, 2012. Below are the symptom and SAP recommended solution.

Description

Symptom

The application WS_DESIGN_TOOL in the CRM WebClient UI 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

Implement the source code corrections for your release.

Reason and prerequisites

The application WS_DESIGN_TOOL within the CRM WebClient UI does not sufficiently encode the URL for display of ATP results, 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 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.
