Unauthorized modification of displayed content in ITS, SAP security note 1512134

SAP security note 1512134, "Unauthorized modification of displayed content in ITS", is a program error note released on 11.01.2011. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

The ITS can be abused by a malicious user allowing them to modify displayed application content without authorization and to potentially obtain authentication information from other legitimate users.

Solution

Apply support package.

Reason and prerequisites

Pages within the ITS do not sufficiently encode INPUT 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 may use this to impersonate the user and access all information with the same rights as the target user. In case of an administrator being impersonated, a full compromise of the application’s security may occur.
