CVE-2003-1039
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 · uneditedMultiple buffer overflows in the mySAP.com architecture for SAP allow remote attackers to execute arbitrary code via a long HTTP Host header to (1) Message Server, (2) Web Dispatcher, or (3) Application Server.
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 · moderate confidenceMultiple buffer overflow vulnerabilities exist in the mySAP.com architecture components (Message Server, Web Dispatcher, and Application Server). Remote attackers can trigger these overflows by sending HTTP requests with an excessively long Host header, potentially allowing arbitrary code execution on the affected SAP systems.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify running SAP Message ServerCheck for sapmsg.exe process or scan for port 3601 (default Message Server port) using netstat -an | findstr 3601 or similar network scanAffected if SAP Message Server process is running and listening on network ports
-
Identify running SAP Web DispatcherCheck for sapwebdisp.exe process or scan for HTTP ports (80, 443, 8000, 8080, 8443) with service signature matching SAP Web DispatcherAffected if SAP Web Dispatcher is running and accessible via HTTP/HTTPS
-
Identify running SAP Application ServerCheck for sapctrl.exe, saposcol.exe processes or scan for SAP application server ports (8000-8009, 8100-8109)Affected if SAP Application Server ABAP or Java stack is running and listening on network ports
-
Verify HTTP exposure of SAP componentsSend a crafted HTTP request to identified SAP HTTP services and inspect the Server header response for SAP signaturesAffected if HTTP endpoints responding with SAP Server headers are found and the Host header can be manipulated
If any of the three SAP components (Message Server, Web Dispatcher, or Application Server) are running and accessible via HTTP, the environment is affected since all versions are vulnerable to the Host header buffer overflow.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply relevant SAP security patches for the Message Server, Web Dispatcher, and Application Server components. Consider implementing input validation at network perimeter devices to filter abnormally long HTTP Host headers until patches can be applied.
