SAP Landscape Transformation (SLT) allows an attacker with user privileges to exploit a vulnerability in the function module exposed via RFC. This flaw enables the injection of arbitrary ABAP code into the system, bypassing essential authorization checks. This vulnerability effectively functions as a backdoor, creating the risk of full system compromise, undermining the confidentiality, integrity and availability of the system.
