SAP security note 2227310, “Unauthorized modification of displayed content in com.sap.portal.themes.integrity”. Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
com.sap.portal.themes.integrity 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
Check on the server side and validate the input values that were submitted.
Reason and prerequisites
com.sap.portal.themes.integrity does 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.
