SEH frame overwrite at offset 2086 in overflow buffer
  • Detect HTML pages containing an EMBED element with an excessively long SRC attribute (>2000 characters), characteristic of the WMP plugin overflow exploit.
  • Detect heap spray pattern using repeated %u4141 Unicode escape sequences in JavaScript unescape() calls within HTML pages served to Firefox/Opera on Windows.
  • Detect HTTP responses with Content-Type text/html serving EMBED tags with .wmv SRC values exceeding 2000 bytes, targeting the WMP plugin overflow at offset ~2082-2090.
  • Characters with the sign bit set (>0x7F) are stripped from the overflow buffer; payloads will be restricted to 7-bit ASCII (BadChars: 0x80-0xFF), aiding in distinguishing exploit traffic.
  • ·The vulnerability only affects the WMP plugin when used in non-Microsoft browsers (Firefox, Opera, etc.) set as the default handler for media files; Internet Explorer is not affected.
  • ·The Metasploit module does not detect Windows SP level or WMP version from the User-Agent alone; target address selection may be inaccurate, affecting reliability of detection signatures based on specific return addresses.
