Remediation
Update SAP Landscape Transformation Multiple Products to the latest version. Monitor for exploitation attempts and review access logs.
Executive Summary:
A critical vulnerability has been identified in SAP Landscape Transformation (SLT) products, assigned a CVSS score of 9.9. An attacker with existing user credentials can exploit this flaw to inject and execute arbitrary code on the SAP system, potentially leading to a complete compromise of business data, disruption of critical operations, and full administrative control over the affected application. Immediate patching is required to mitigate the severe risk to the organization's core business functions.
Vulnerability Details
CVE-ID: CVE-2025-42950
Affected Software: SAP Landscape Transformation Multiple Products
Affected Versions: See vendor advisory for specific affected versions
Vulnerability: The vulnerability exists within a function module exposed via the Remote Function Call (RFC) interface in SAP SLT. An authenticated attacker, even with low-level user privileges, can send a specially crafted RFC request to this function module. Due to insufficient input validation, the attacker's malicious payload is interpreted and executed as ABAP code, resulting in Remote Code Execution (RCE) on the SAP application server. This allows the attacker to operate with the privileges of the SAP system service, enabling them to read, modify, or delete sensitive business data, manipulate system processes, and escalate their privileges.
Business Impact
This vulnerability is rated as critical severity with a CVSS score of 9.9. Exploitation could have catastrophic consequences for the organization. An attacker could gain complete control over the SAP system, leading to the theft or manipulation of highly sensitive financial, customer, and employee data. This could result in significant financial fraud, disruption of mission-critical business processes like supply chain and manufacturing, severe reputational damage, and major regulatory fines for non-compliance with standards such as SOX and GDPR. The ability to execute code directly on the SAP server effectively hands the keys to the kingdom to an attacker, posing an existential threat to business integrity and continuity.
Remediation Plan
Immediate Action: The primary remediation is to apply the security patches provided by the vendor immediately. Administrators must update SAP Landscape Transformation Multiple Products to the latest version that addresses this vulnerability. After patching, it is crucial to review system access logs for any signs of compromise that may have occurred prior to the update.
Proactive Monitoring: Implement enhanced monitoring of RFC traffic. Specifically, security teams should look for unusual or unauthorized calls to function modules, especially from unexpected user accounts or source systems. Review the SAP Security Audit Log (transaction SM20) for suspicious activities, such as unauthorized code execution, privilege escalation attempts, or unexpected changes to system configurations. Monitor for the creation of new or modified ABAP programs outside of normal development cycles.
Compensating Controls: If patching cannot be performed immediately, implement the following controls to reduce the attack surface:
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of the publication date of August 12, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, given the critical severity and the high value of SAP systems, it is highly probable that threat actors will prioritize developing an exploit. The vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog, but organizations should treat it as an imminent threat.
Analyst Recommendation
This vulnerability represents a critical and immediate threat to the organization. Due to the 9.9 CVSS score and the potential for complete system compromise, we strongly recommend that immediate action is taken to apply the vendor-supplied patches across all affected SAP SLT systems. This vulnerability should be treated as the highest priority for your SAP security and basis teams. While it is not yet on the CISA KEV list, its severity makes it a prime candidate for future inclusion. If patching is delayed for any reason, the compensating controls and proactive monitoring recommendations must be implemented without delay to mitigate risk.
