Unauthorized modification of stored content in RWB, SAP security note 1828988

SAP security note 1828988, "Unauthorized modification of stored content in RWB", is a program error note released on 08.10.2013. Below are the symptom and SAP recommended solution.

Description

Symptom

PI Runtime Workbench (RWB) can be abused by attackers, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.

Solution

This issue is fixed with the Support Packages and Patches of the Software Components referenced by this note in the section ‘SP Patch Level’.

Reason and prerequisites

Web pages within ‘Process Integration Runtime Workbench’ result in a stored cross-site scripting issue. It can be used to permanently modify displayed content from a Web site, allowing the attacker to embed content that is rendered automatically, without the attacker having to target victims individually. Stored cross-site scripting can also 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.
