  • Detect instantiation of the lrFileIOService ActiveX control by its CLSID {8D9E2CC7-D94B-4977-8510-FB49C361A139} in browser traffic or registry; exploitation abuses the WriteFileString method to drop a malicious DLL.
  • Monitor for creation of LrWeb2MdrvLoader.dll in unexpected directories, followed by a LoadLibrary call from the lrMdrvService ActiveX control's Init() method — this is the payload staging mechanism.
  • Target fingerprinting in the exploit checks for Windows NT 5.1 (XP) and MSIE in the User-Agent; alert on IE 6.0–8.0 requests to suspicious pages that instantiate this CLSID.
  • The exploit delivers an HTML page with embedded JavaScript that calls WriteFileString to write a DLL and then calls lrMdrvService.Init(); inspect HTML responses containing both the CLSID and Init() invocations.
  • ·The Metasploit module only targets IE 6.0–8.0 on Windows XP (NT 5.1); exploitation is blocked on Windows Vista and 7 due to Low Integrity Process virtualization redirecting the dropped DLL to a virtualized folder not used by LoadLibrary.
  • ·The vulnerability affects HP LoadRunner versions before 11.52; version 11.50 is explicitly confirmed as vulnerable in the exploit module.
