Unauthorized modification of displayed content in IC Manager, SAP security note 1574226

SAP security note 1574226, "Unauthorized modification of displayed content in IC Manager", is a program error note released on 09.08.2011. Below are the symptom and SAP recommended solution.

Description

Symptom

The Internet Communication Manager 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

Please apply the support package mentioned in this note, or the respective correction instruction.

Reason and prerequisites

Pages within the Internet Communication Manager 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 web site. 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 can occur.
