Unauthorized modification of displayed content in CA-GTF-RCM, SAP security note 1700532

SAP security note 1700532, “Unauthorized modification of displayed content in CA-GTF-RCM”, is a program error note released on February 12, 2013. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

CA-GTF-RCM can be abused by an attacker, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.

Solution

Apply this note.

Reason and prerequisites

Several BSP pages within CA-GTF-RCM do not sufficiently encode INPUT & 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.

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.
