Detection & IOCsextracted from sources · hover to see the quote
- →Monitor IMAP server responses containing backquote characters (`) in mailbox names, particularly during subscription or unsubscription operations, as these can trigger arbitrary command execution in vulnerable Mutt/NeoMutt clients. ↗
- →Detect exploitation attempts via $imap_check_subscribed or the browser menu subscription function in Mutt; a malicious IMAP server can inject commands through improperly parsed mailbox names. ↗

CVE-2018-14354 [CRITICAL] CVE-2018-14354 mutt: Remote code injection vulnerability to an IMAP mailbox
CVE-2018-14354 mutt: Remote code injection vulnerability to an IMAP mailbox
A flaw was found in mutt before 1.10.1. When "subscribing" to an IMAP mailbox, either via $imap_check_subscribed, or via the
function in the browser menu, the lack of proper input parsing may lead to remote code injection from a malicous IMAP server.
