Buffer overflow vulnerability in the HTTP receiver ISAPI extension (BizTalkHTTPReceive.dll) of Microsoft BizTalk Server 2002 allows remote attackers to execute arbitrary code via crafted HTTP requests to the HTTP receiver function.

MitigationApply Microsoft security patch for CVE-2003-0117 if available; otherwise, disable the BizTalk HTTP receiver ISAPI extension or filter HTTP traffic to the affected endpoint until patching or upgrade to a supported BizTalk Server version can be completed.

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 installed BizTalk Server version
    Check the installed BizTalk Server version via Windows Add/Remove Programs, or check the BizTalk Server Administration documentation, or look at the BizTalk Server installation directory for version information.
    Affected if The installed version is Microsoft BizTalk Server 2002 exactly (version 6.0 or 6.1 in some listings)
  2. Locate BizTalkHTTPReceive.dll
    Search for BizTalkHTTPReceive.dll on the system - typically found in the BizTalk Server installation path or in the IIS scripts/bin directory used for ISAPI extensions.
    Affected if The file BizTalkHTTPReceive.dll exists on the server in an ISAPI extensions directory
  3. Verify HTTP receiver ISAPI extension is registered in IIS
    Open IIS Manager, expand the server node, click on 'ISAPI and CGI Restrictions' or check the Web Service Extension configuration to see if BizTalk HTTP Receive is listed as an allowed extension.
    Affected if The BizTalk HTTP Receive ISAPI extension is registered and allowed in IIS
  4. Confirm HTTP receiver endpoint is configured and accessible
    Check BizTalk Server configuration for HTTP receiver ports, or test access to the configured HTTP receive URL (typically with a path like /BTSHTTPReceive.dll or similar).
    Affected if An HTTP receive location is enabled and configured to accept HTTP requests on any port or path

A system is affected if BizTalk Server 2002 is installed with the BizTalkHTTPReceive.dll ISAPI extension enabled and an active HTTP receiver endpoint configured to accept HTTP traffic.
