Unspecified vulnerability in the Sound component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, 1.4.2_25, and 1.3.1_27 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is an uncontrolled array index that allows remote attackers to execute arbitrary code via a MIDI file with a crafted MixerSequencer object, related to the GM_Song structure.

  • Detect delivery of a crafted RMF file containing an embedded MIDI with a malicious controller event served over HTTP, identifiable by Content-Type 'application/octet-strem' (note the typo used by the exploit module).
  • Monitor HTTP responses serving files with a .rmf extension, especially when followed by a .jar file request from the same browser session, as the exploit delivers both an RMF and a JAR payload.
  • Alert on Java processes loading or playing RMF/MIDI files that trigger MixerSequencer object instantiation, particularly where EBX register is used as a jump target pointing into MIDI file data (shellcode stored in a fake MIDI event).
  • The exploit uses a SONG block inside an RMF file to populate the GM_Song structure with an attacker-controlled function pointer; inspect RMF files for SONG blocks containing unexpected pointer-sized values.
  • The exploit uses 'migrate -f' as an InitialAutoRunScript, meaning post-exploitation process migration will occur immediately; monitor for unexpected child process spawning from java.exe or javaw.exe shortly after RMF/MIDI file access.
  • ·The exploit targets Java 6 Update 18 and earlier (also 6u17 confirmed); the ROP gadget address 0x7C35A78D (jmp ebx in msvcr71.dll) is version-specific and may not apply to other Java or Windows configurations.
  • ·The exploit platform is Windows only; the jmp-ebx gadget from msvcr71.dll is a Windows-specific DLL and this technique does not apply to Linux/macOS Java deployments.
  • ·The Content-Type value used in the exploit ('application/octet-strem') contains a deliberate typo; detection rules matching the standard 'application/octet-stream' spelling will miss this specific exploit delivery.
