Severity 30
Port 143
Protocol TCP
Class IMAP
Detailed Description A version of Alt-N MDaemon IMAP Server which is older than version 8.1.5 is detected as running on the host. Alt-N MDaemon is an SMTP/IMAP server for Microsoft Windows operating systems. MDaemon versions prior to 8.1.5 could allow a remote attacker to cause a denial of service, caused due to an input validation error in the IMAP service that does not properly handle email folder names containing format string specifiers. A remote, authenticated attacker could exploit this vulnerability to cause the application to crash or consume a large amount of system resources.

* Note: This check solely relied on the banner of the remote IMAP server to assess this vulnerability, so this might be a false positive.
