Unauthorized modification of displayed content in PLM-CFO(11, SAP security note 1694077

SAP security note 1694077, "Unauthorized modification of displayed content in PLM-CFO", is a program error note released on May 8, 2012. Below are the symptom and SAP recommended solution.

Description

Symptom

The PLM-CFO 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

The program corrections are contained in the Correction Instructions tab of this note. You need to implement the corrections in your system.

Reason and prerequisites

Pages within the PLM-CFO do not sufficiently encode input and 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 website. Additionally, it 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 impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, a full compromise of the application’s security may occur.
