CVE-2025-31330
Remediation / Mitigation Strategy: CVE-2025-31330 - SAP Landscape Transformation (SLT) ABAP Code Injection
Description of Vulnerability:
SAP Landscape Transformation (SLT) contains an ABAP code injection vulnerability within a function module exposed via RFC. An attacker with valid, but potentially low-privileged, user credentials can exploit this flaw to inject arbitrary ABAP code into the SAP system. This bypasses authorization checks designed to prevent such actions.
Severity:
Critical. CVSS Score: 9.9
Known Exploit:
The vulnerability can be exploited by crafting malicious RFC calls to the vulnerable function module within SLT. The injected ABAP code executes with the privileges of the calling user, effectively creating a backdoor for full system compromise.
Remediation/Mitigation Strategy:
Immediate Actions:
Apply Security Patch: Immediately apply the security patch provided by SAP to address CVE-2025-31330. This is the primary and most effective remediation step. Refer to SAP Security Note associated with CVE-2025-31330 for specific patch details and instructions.
Restrict RFC Access: Until the patch is applied, restrict access to the vulnerable RFC function module. Identify the specific function module (refer to SAP Security Note for details) and limit access to only trusted users and systems that require it for legitimate business purposes. This can be achieved through RFC authorization objects and profile maintenance in SAP.
Monitor System Logs: Increase monitoring of SAP system logs (SM20, SM21) and security audit logs (SM19, SM20) for suspicious activity related to RFC calls to SLT modules. Specifically, look for unusual ABAP code execution, authorization errors related to RFC, and changes to critical system objects.
Long-Term Actions:
Principle of Least Privilege: Review and enforce the principle of least privilege for all SAP users, including those using SLT. Ensure users only have the minimum necessary authorizations to perform their job functions.
Secure Development Practices: Implement secure ABAP coding practices, including input validation, output encoding, and authorization checks, to prevent future code injection vulnerabilities. Conduct code reviews and static analysis to identify potential security flaws.
Regular Security Audits: Conduct regular security audits of the SAP environment, including SLT configurations and code, to identify and address potential vulnerabilities. Use SAP’s security tools and third-party security scanners to automate this process.
Vulnerability Management Program: Establish a comprehensive vulnerability management program to track and remediate security vulnerabilities in a timely manner. This includes staying informed about SAP security notes and applying patches promptly.
Implement Monitoring and Alerting: Implement robust monitoring and alerting mechanisms to detect suspicious activities and potential security breaches. Define clear incident response procedures to handle security events effectively.
Important Considerations:
- Consult the official SAP Security Note associated with CVE-2025-31330 for the most accurate and up-to-date information.
- Test the patch in a non-production environment before applying it to the production system.
- Communicate the vulnerability and remediation steps to relevant stakeholders, including IT staff, security personnel, and business users.
- Maintain a record of all remediation activities.
