Unauthorized modification of displayed content, SAP security note 1495663

SAP security note 1495663, “Unauthorized modification of displayed content”, is a note. Below are the symptom and SAP recommended solution.

Description

Symptom

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

Solution

Apply the attached correction instructions provided in the SAP Note.

Reason and prerequisites

Several pages within the Campaign Automation BSP application do not sufficiently encode 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. In case an administrator is impersonated, a full compromise of the application’s security may occur.
