Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Due to an OS Command Injection vulnerability in SAP Application Server for ABAP and SAP NetWeaver RFCSDK, an authenticated attacker with administrative access and adjacent network access could upload specially crafted content to the server. If processed by the application, this content enables execution of arbitrary operating system commands. Successful exploitation could lead to full compromise of the system�s confidentiality, integrity, and availability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OS Command Injection vulnerability in SAP Application Server for ABAP and SAP NetWeaver RFCSDK allows an authenticated attacker with administrative privileges to upload specially crafted content that, when processed by the application, enables execution of arbitrary operating system commands, leading to full system compromise.

MitigationApply SAP security notes/patches for this vulnerability immediately. Additionally, implement strict input validation on file uploads, avoid using user-controlled content in OS commands, and restrict administrative access and network adjacency to minimize attack surface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SAP ABAP or NetWeaver RFCSDK installation
    Run transaction SM37 or use SAPMMC to identify the SAP system version and components. Check for SAP Application Server for ABAP or NetWeaver RFCSDK in the installed product list.
    Affected if The system runs SAP Application Server for ABAP or SAP NetWeaver RFCSDK and the version is within the affected range (if known) or unpatched.
  2. Verify administrative user access configuration
    Use transaction SU01 or SAP Identity Management to review user roles. Check if untrusted or non-essential users hold SAP_ALL, SAP_NEW, or administrative roles (such as S_ADMI_FCD with privileged permissions).
    Affected if Non-administrative or untrusted authenticated users possess administrative or elevated privileges.
  3. Check for enabled file upload capabilities
    Review SAP transaction code SCMS or verify RFC-enabled function modules that accept uploaded content (such as SCMS_BINARY_TO_XSTRING, SCMS_UPLOAD). Use transaction SE37 to inspect function module authorizations.
    Affected if File upload functionality or RFC interfaces that accept external content are exposed without strict authorization controls.
  4. Inspect recent file upload logs for anomalies
    Use transaction SM37 or log viewer (transaction SLG1) for logs related to upload transactions (such as CG3Y, CG3Z, or custom upload programs). Look for uploads from untrusted administrative users.
    Affected if Unexpected or suspicious file uploads have been performed by authenticated users with administrative privileges.
  5. Review operating system command execution logs
    Check SAP system logs (transaction SM37, ST03N) and OS-level audit logs for unusual command execution patterns. Look for unexpected calls to transaction SE38 or SM49/SM69 that execute OS-level commands.
    Affected if Operating system commands have been executed from the SAP application layer outside of documented administrative procedures.

A system is affected if it runs SAP Application Server for ABAP or NetWeaver RFCSDK with an unpatched version, has authenticated users with administrative privileges, and exposes file upload or RFC functionality that could be leveraged for command injection.
