SAP security note 1676848, “Unauthorized modification of BSP in CRM-IC-OBJ”. Below are the symptom and SAP recommended solution.
Description
Symptom
Application Component CRM-IC-OBJ can be abused by a malicious user, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.
Solution
Please apply this note or import the changes via the relevant support package.
Reason and prerequisites
BSP Page CRM_IC_AUTO/RuntimeRepository.xml within Application Component CRM-IC-OBJ does not sufficiently encode OUTPUT parameters, resulting in a cross-site scripting issue.
Cross-site scripting can be used to steal another user’s authentication information, such as data relating to their current session. A malicious user 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.
