Unauthorized modificat. of displ. content in CRM-BTX-PRV-DUI, SAP security note 1676514

SAP security note 1676514, “Unauthorized modification of displayed content in CRM-BTX-PRV-DUI”, released on 08.05.2012. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

CRM-BTX-PRV-DUI 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

Implement this note.

Reason and prerequisites

BSP applications PROVDL_DET, PROVDL_MAIN, PROVDLFRAME, and PROVDLNV within CRM-BTX-PRV-DUI 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.

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.
