Detection & IOCsextracted from sources · hover to see the quote
- →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. ↗

HP LoadRunner lrFileIOService ActiveX WriteFileString Remote Code Execution
This module exploits a vulnerability on the lrFileIOService ActiveX, as installed with HP LoadRunner 11.50. The vulnerability exists in the WriteFileString method, which allow the user to write arbitrary files. It's abused to drop a payload embedded in a dll, which is later loaded through the Init() method from the lrMdrvService control, by abusing an insecure LoadLibrary call. This module has been tested successfully on IE8 on Windows XP. Virtualization based on the Low Integrity Process, on Windows Vista and 7, will stop this module because the DLL will be dropped to a virtualized folder, which isn't used by LoadLibrary.
