Overview
CVE-2025-42950 is a severe vulnerability in SAP Landscape Transformation (SLT) that provides an attacker with system-level access, jeopardizing the safety and security of the entire system. This flaw, impacting systems that employ SAP Landscape Transformation, functions as a backdoor, enabling malicious users to inject arbitrary ABAP code into the system without the necessary permissions. The vulnerability is of critical concern not only because it bypasses essential authorization checks, but also because it exposes the system to potential compromise, undermining the confidentiality, integrity, and availability of the system.

How the Exploit Works
The exploit takes advantage of a vulnerability within the function module of SAP Landscape Transformation (SLT) that is exposed via RFC. This flaw allows a malicious actor to inject arbitrary ABAP code into the system, bypassing essential authorization checks. This unauthorized code injection can then be used by the attacker to manipulate the system, potentially leading to full system control and data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
DATA: lv_inject_code TYPE string.
lv_inject_code = 'malicious ABAP code'.
CALL FUNCTION 'SAP_SLT_VULNERABLE_FM' IN SAP SYSTEM
EXPORTING
injection_code = lv_inject_code.In this pseudo-code, a malicious actor injects malicious ABAP code into the vulnerable function module. This code can then be executed within the system, bypassing authorization checks, and potentially leading to a full system compromise.
Mitigation Guidance
To mitigate the threat posed by CVE-2025-42950, it is recommended that organizations apply the vendor’s patch as soon as it becomes available. Until then, utilizing Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) may serve as a temporary mitigation technique. However, these solutions should not be seen as a long-term fix but rather a temporary measure until the vendor’s patch can be applied. Regular monitoring and updating of systems should be part of an organization’s standard cybersecurity protocol to protect against such threats.
