SAP Security Note
High priority
SAP security note 1656549, “Unauthorized change of displayed content in Usermanagement”, is a program error note released on 13.03.2012. Below are the symptom and SAP recommended solution.
Description
Symptom
Portal usermanagement 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
Update your AS Java to a Support Package (SP) or release where the issue is fixed. See the “Support Package Patch” section below for details and available patches.
Reason and prerequisites
Pages within Portal usermanagement 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 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.
