Introduction
SAP S/4HANA, a cornerstone of enterprise resource planning, faces a significant threat from CVE-2025-43010, a vulnerability that allows attackers to remotely inject and replace ABAP programs. This flaw, rated high severity (CVSS 8.3), could severely disrupt business operations and compromise system integrity.
Technical Information
The vulnerability specifically affects SAP S/4HANA Cloud Private Edition and On-Premise installations within the SCM Master Data Layer (MDL). Due to inadequate input validation and missing authorization checks, attackers with standard SAP authorization can remotely execute a vulnerable function module. This exploitation enables the injection and replacement of arbitrary ABAP programs, including critical SAP-standard programs.
The root cause is directly linked to CWE-94 (Code Injection), where the lack of proper validation allows attackers to manipulate ABAP code execution remotely. Exploitation involves authenticating with standard SAP credentials, executing the vulnerable function module, and injecting malicious ABAP code to overwrite existing programs.
Patch Information
SAP has addressed this vulnerability in Security Note 3600859. Immediate patch application is strongly recommended. Organizations should also restrict access to the affected function module through SAP authorization objects (e.g., S_RFC) and enforce strict RBAC.
Detection Methods
Organizations should monitor SAP systems for unusual ABAP program modifications, particularly through transaction logs (e.g., SE38, SE80). Regular auditing of custom code and monitoring of user activities, especially those with standard authorizations, can help detect potential exploitation attempts.
Vendor Security History
SAP has previously addressed similar ABAP-related vulnerabilities, demonstrating a consistent and timely response through its regular SAP Security Patch Day cycle. This proactive approach underscores the importance of promptly applying available patches and following SAP's security advisories closely.
