SAP Security Note
High priority
SAP security note 1685251, “Unauthorized modification of BSP in FI-CA”, is a program error note released on 08.05.2012. Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
FI-CA 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
Implement this SAP Note or make the changes by importing the relevant Support Package.
Reason and prerequisites
BSP pages FKK_CRM_IC_F4 in FI-CA do not sufficiently encode OUTPUT parameters, resulting in a reflected cross-site scripting issue.
Stored cross-site scripting can also 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.
