MailEnable SMTP Service Denial of Service Vulnerabilities (ME-10044)

medium Nessus Plugin ID 49284


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote mail server is prone to denial of service attacks.


The SMTP service (MESMTPC.exe) included with the version of MailEnable on the remote host reportedly does not properly check the length of either the email address used in a 'MAIL FROM' command or the domain name in a 'RCPT TO' command before using it in a log message.

A malicious attacker may be able to leverage these issues to trigger an unhandled invalid parameter error and cause the affected SMTP service to crash.


Either apply Hotfix ME-10044 or upgrade to MailEnable 4.26 or later.
