CVE-2025-42880 Overview
CVE-2025-42880 is a critical code injection vulnerability in SAP Solution Manager caused by missing input sanitation when calling a remote-enabled function module. This vulnerability allows an authenticated attacker to insert malicious code that could provide full control over the affected system, resulting in severe impacts to confidentiality, integrity, and availability.
Critical Impact
Authenticated attackers can achieve full system compromise through code injection in remote-enabled function modules, leading to complete control over SAP Solution Manager deployments.

Technical Details for CVE-2025-42880
Vulnerability Analysis
This vulnerability is classified as CWE-94 (Improper Control of Generation of Code, or 'Code Injection'). The flaw exists in SAP Solution Manager's handling of user-supplied input when processing calls to remote-enabled function modules. Due to the absence of proper input sanitation, an authenticated attacker can craft malicious payloads that are interpreted and executed as code within the application context.
The network-accessible nature of this vulnerability combined with low attack complexity makes it particularly dangerous in enterprise environments. While authentication is required, the ability to achieve full system compromise elevates the risk substantially. The changed scope indicator suggests that successful exploitation can affect resources beyond the vulnerable component's security scope, potentially impacting other connected SAP systems or infrastructure.
Root Cause
The root cause of CVE-2025-42880 is the absence of proper input validation and sanitization mechanisms when processing data passed to remote-enabled function modules in SAP Solution Manager. The application fails to adequately filter or escape user-controlled input before incorporating it into dynamically generated code or command structures, enabling injection attacks.
Attack Vector
The attack is network-based and can be executed remotely by any authenticated user with access to the vulnerable remote-enabled function modules. An attacker would craft a specially formatted request containing malicious code payloads and submit it through the normal function module interface. The lack of input sanitation allows the injected code to execute with the privileges of the SAP Solution Manager application, potentially granting complete control over the system including the ability to read, modify, or delete data, execute arbitrary commands, and pivot to other connected systems.
Detection Methods for CVE-2025-42880
Indicators of Compromise
- Unusual or unexpected calls to remote-enabled function modules containing special characters or code-like syntax
- Anomalous process execution originating from SAP Solution Manager application processes
- Unexpected system modifications or data access patterns following function module calls
- Authentication logs showing successful logins followed by unusual RFM activity
Detection Strategies
- Monitor SAP transaction logs for suspicious activity patterns in function module calls
- Implement application-level logging to capture all inputs to remote-enabled function modules
- Deploy network monitoring to detect anomalous traffic patterns to SAP Solution Manager interfaces
- Utilize SAP Security Audit Log (SM21) to track potential exploitation attempts
Monitoring Recommendations
- Enable comprehensive logging for all remote function call activity in SAP Solution Manager
- Configure alerts for function module calls containing unexpected input patterns or known injection signatures
- Monitor system integrity for unauthorized changes following SAP Solution Manager interactions
- Review user access logs for accounts making unusual function module calls
How to Mitigate CVE-2025-42880
Immediate Actions Required
- Apply the security patch referenced in SAP Note #3685270 immediately
- Review and restrict access to remote-enabled function modules to only necessary users
- Implement additional input validation at the network perimeter where possible
- Audit current user access rights to SAP Solution Manager and apply principle of least privilege
Patch Information
SAP has released a security update addressing this vulnerability as part of their Security Patch Day. Administrators should consult SAP Note #3685270 for detailed patch installation instructions and version-specific guidance. Additional information is available on the SAP Security Patch Day portal.
Workarounds
- Restrict network access to SAP Solution Manager to trusted networks only until patching is complete
- Implement additional authentication controls or multi-factor authentication for users accessing affected function modules
- Deploy web application firewall rules to filter potentially malicious payloads targeting the vulnerable functionality
- Consider temporarily disabling non-essential remote-enabled function modules until the patch can be applied
