Unauthorized modification of displayed content in CRMCMP_SCR, SAP security note 1494173

SAP security note 1494173, "Unauthorized modification of displayed content in CRMCMP_SCR", is a program error note released on 14.12.2010. Below are the symptom and SAP recommended solution.

Description

Symptom

The CRMCMP_SCR, CRMCMP_SCR_CHAT, and CRMCMP_SCR_MAIN BSP applications 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 or apply the relevant support package.

Reason and prerequisites

The following BSP pages do not sufficiently encode the input parameters, resulting in a reflected cross-site scripting issue:

• CRMCMP_SCR\session_buffered_frame.htm
• CRMCMP_SCR\session_single_frame.htm
• CRMCMP_SCR\LeadReturn.htm
• CRMCMP_SCR_CHAT\session_buffered_frame.htm
• CRMCMP_SCR_CHAT\session_single_frame.htm
• CRMCMP_SCR_MAIN\session_buffered_frame.htm
• CRMCMP_SCR_MAIN\session_single_frame.htm

A reflected cross-site scripting attack can be used to non-permanently deface or modify displayed content from a website and steal another user’s authentication information, such as data relating to their current session. An attacker who gains access to this data could impersonate the user and access all information with the same rights as the target user.
