Mailtraq SMTP commands denial of service
| mailtraq-smtp-command-dos (12309) |  Low Risk |
Description:
Mailtraq is vulnerable to a denial of service. By establishing an SMTP connection and issuing the 'HELO', 'MAIL FROM', 'RCPT TO' or 'FROM' command followed by a specially-crafted string, a remote attacker can cause the server to consume 100% of the available CPU resources, which would result in a denial of service for legitimate users.
Platforms Affected:
- Fastraq, Mailtraq 2.1.0.1302
Remedy:
Upgrade to the latest version of Mailtraq (2.3.2.1419 or later), available from the Mailtraq Web site. See References.
Consequences:
Denial of Service
