PI SEC Unauthorized modification of displayed content in PI, SAP security note 1788080

SAP security note 1788080, “PI SEC: Unauthorized modification of displayed content in PI”, is a program error note released on 14.01.2014. Below are the symptom and SAP recommended solution.

Description

Symptom

The ESR application 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 ‘Support Package Patches’ section.

Reason and prerequisites

A web page within ESR does not sufficiently encode 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 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.
