MailEnable SMTP Connector Multiple NTLM Authentication Vulnerabilities

high Nessus Plugin ID 22483
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 SMTP server is affected by multiple vulnerabilities.


The remote host is running MailEnable, a commercial mail server for Windows.

The version of MailEnable Professional or MailEnable Enterprise installed on the remote host has several problems involving its support of NTLM authentication. A remote, unauthenticated attacker can leverage these flaws to execute arbitrary code on the remote host or crash the SMTP connector.

Note that NTLM authentication is not enabled in MailEnable by default but is on the remote host.


Apply the ME-10015 hotfix referenced in the vendor link above.
