SAP Security Note
High priority
SAP security note 1640304, “Unauthorized modification of displayed content in SAML2”, is a program error note released on 20.02.2012. Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
The implementation of SAML 2.0 has an XSS vulnerability and 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 the appropriate corrections.
Reason and prerequisites
Prerequisite: Note 1582870 has been implemented, or a Support Package has been imported that contains this note.
Reason: Components within SAML 2.0 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. It can also 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.
