  • The Metasploit module targets Windows XP SP2/SP3 with IE6; the payload uses a pop/pop/ret gadget in msls31.dll (IE6) at 0x746C15A9 and a jmp esp in user32.dll at 0x774699bf — these ROP gadget addresses can be used as memory-pattern indicators in exploit traffic.
  • The exploit is delivered as a malicious webpage; monitor for HTML responses containing both an ActiveX object tag referencing NCTAudioFile2 and a call to SetFormatLikeSample with a large string (>4000 chars).
  • The PoC2 (shinnai) uses a 4116-byte 'A' buffer before the EIP overwrite; a string of 4116+ identical characters passed to SetFormatLikeSample is a reliable detection heuristic.
  • ·The ROP/return gadget addresses (0x746C15A9 in msls31.dll, 0x774699bf and 0x77D7AAEB in user32.dll) are OS/patch-level specific and will not be reliable across different Windows versions or patch levels.
  • ·On Windows XP SP2 with IE7, the exploit results in a DoS (IE crash) rather than reliable RCE without a debugger attached; RCE was only confirmed on Win2k SP4 with IE6.
