Unrestricted file upload vulnerability in the Document Conversions Launcher Service in Microsoft Office SharePoint Server 2007 SP2, when the Document Conversions Load Balancer Service is enabled, allows remote attackers to execute arbitrary code via a crafted SOAP request to TCP port 8082, aka "Malformed Request Code Execution Vulnerability."

pathWINDOWS\system32\wbem\mof\
commandSOAP ConvertFile / ConvertFileRequest to HtmlTrLauncher with directory traversal via ..\ sequences
  • Detect inbound SOAP requests to TCP port 8082 targeting the HtmlTrLauncher endpoint, especially ConvertFile requests containing directory traversal sequences ('..\') in the destination filename field.
  • Alert on unexpected .exe or .mof files written to WINDOWS\system32\ or WINDOWS\system32\wbem\mof\ by the SharePoint Document Conversions Launcher Service process, as the exploit drops a payload EXE and a WMI MOF file for execution.
  • Monitor for WMI MOF file drops (random-named .mof files) in WINDOWS\system32\wbem\mof\ as the exploit uses the WbemExec technique to achieve SYSTEM-level code execution.
  • Look for HTTP responses containing 'ConvertFileResponse' and 'CE_OTHER' on port 8082 as indicators of successful exploitation.
  • The default traversal depth is 7 levels ('..\' repeated 7 times); network signatures should match SOAP bodies on port 8082 containing multiple consecutive '..\' sequences in filename parameters.
  • ·The vulnerability is only exploitable when the Document Conversions Load Balancer Service is explicitly enabled on SharePoint Server 2007 SP2; installations without this service enabled are not affected.
  • ·The Metasploit module's WbemExec payload delivery technique is specific to Windows Server 2003 SP2 targets; exploitation behavior may differ on other OS versions.
  • ·The traversal depth (default 7) may need to be adjusted depending on the installation path depth of the target SharePoint server; detections relying on a fixed number of traversal sequences may miss variants with different DEPTH values.
