Unauthorized modification of displayed content CCS BCB apps, SAP security note 1585652

SAP security note 1585652, “Unauthorized modification of displayed content CCS BCB apps”, is a program error note released on 11.10.2011. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

Contact Center Simulator and Business Communication Broker applications 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

Update to the fixed version. See the Support Package Patch section below for details.

Reason and prerequisites

Most of the JSP pages within CCS and BCB applications 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 Web site.

Reflected cross-site scripting can be used to steal another user's authentication information, such as data relating to their current session. A malicious user 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.
