bytes
\x90 * 556 + rop_chain + \x90 * 20 + \xCC * remainder (total ~1500 bytes), base64-encoded, prefixed with '&', sent as IMAP EXAMINE mailbox argument
  • Detect oversized IMAP EXAMINE commands: alert on EXAMINE commands with mailbox name arguments exceeding normal length (exploit uses ~1500 bytes base64-encoded, prefixed with '&'), especially on TCP port 143.
  • The exploit payload is base64-encoded and prefixed with '&' in the EXAMINE mailbox argument — inspect IMAP EXAMINE commands for '&' followed by a large base64 blob on port 143.
  • Focus detection on 32-bit Windows Domino servers running nIMAP.EXE; these are at greatest risk as ASLR is less effective on 32-bit platforms.
  • The exploit requires prior authentication (valid IMAP credentials); correlate large EXAMINE payloads with successful LOGIN events from the same session.
  • ·64-bit Domino deployments with ASLR enabled significantly reduce exploitability; 32-bit Windows deployments without ASLR are the primary high-risk targets.
