CVE_2024_49040
What it means
Raw email From header contains multiple parsed/angle-bracket addresses.
Why it fires
CVE-2024-49040 exploits improper P2 FROM header parsing in Microsoft Exchange Server. By including multiple angle-bracket addresses in the From header (non-RFC-compliant syntax), attackers can make the displayed sender address differ from the actual routing address. The rule inspects the raw From line before parser normalization and fires when it contains multiple address markers or parses as multiple mailboxes; it cannot prove the recipient Exchange server was vulnerable.
