  • Detect ActiveX instantiation of CheckOutAndOpenControl (CheckOutAndOpen.dll) in a browser context, particularly calls to the openWebdav() method with an HTTP/UNC URI argument ending in .hta
  • Alert on mshta.exe being spawned as a child of a browser process (e.g. iexplore.exe) with a remote HTTP URL argument ending in .hta — this is the direct execution path triggered by the vulnerable ActiveX control
  • Monitor for HTTP responses with Content-Type: application/hta served to Internet Explorer clients, especially when the request originates from a CheckOutAndOpen ActiveX openWebdav() call
  • Detect wscript.exe executing a randomly-named .vbs file from %TEMP%, followed immediately by execution of a randomly-named .exe from %TEMP% — this is the HTA payload delivery chain used by the exploit
  • The exploit only targets Internet Explorer; requests from non-MSIE user-agents are rejected. Network detection should focus on MSIE user-agent strings fetching .hta resources from attacker-controlled servers.
  • The Metasploit module uses 'migrate -f -k' as InitialAutoRunScript post-exploitation; detect meterpreter process migration activity following mshta.exe execution as a post-compromise indicator
  • ·The exploit targets only Oracle WebCenter Content 11.1.1.6.0 with the CheckOutAndOpenControl ActiveX installed; version 10.1.3.5.1 is also listed as affected per the advisory but was not confirmed in exploit testing
  • ·SMB-based URI delivery is theoretically possible but requires the WebClient service, which is only enabled by default on Windows XP SP3; the HTA/HTTP delivery path is preferred and more broadly applicable
  • ·The exploit is Internet Explorer-only; other browsers will receive a 404 response and the attack will not proceed
