Description

Lotus Notes SMTP MTA is susceptible to being used as a mail relay for SPAM or other unsolicited email. By connecting to the mail server (tcp25) and issuing a 'MAIL FROM' command with <> as the argument, then issuing a specially encapsulated RCPT TO, an unauthorized user can relay email via this server.

An encapsulated address looks like this: encapsulatedaddress@yourdomain.com

where yourdomain.com is the domain of the vulnerable mail server, and encapsulatedaddress is the encoded destination email address. The encoding scheme is as follows: replace "@" with "%".

Solution(s)

  • smtp-domino-0002
