Apache Sling Commons Messaging Mail provides a simple layer on top of JavaMail/Jakarta Mail for OSGi to send mails via SMTPS. To reduce the risk of "man in the middle" attacks additional server identity checks must be performed when accessing mail servers. For compatibility reasons these additional checks are disabled by default in JavaMail/Jakarta Mail. The SimpleMailService in Apache Sling Commons Messaging Mail 1.0 lacks an option to enable these checks for the shared mail session. A user could enable these checks nevertheless by accessing the session via the message created by SimpleMessageBuilder and setting the property mail.smtps.ssl.checkserveridentity to true. Apache Sling Commons Messaging Mail 2.0 adds support for enabling server identity checks and these checks are enabled by default. - https://javaee.github.io/javamail/docs/SSLNOTES.txt - https://javaee.github.io/javamail/docs/api/com/sun/mail/smtp/package-summary.html - https://github.com/eclipse-ee4j/mail/issues/429

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the fd538d14-5778-4764-b321-2ddd61a8a58f advisory.

    Red Hat reports:
    A vulnerability was found in Apache Sling Commons Messaging                 Mail(angus-mail), which provides a simple interface for sending                 emails via SMTPS in OSGi, does not offer an option to enable                 server identity checks, leaving connections vulnerable to                 man-in-the-middle attacks and can allow insecure email                 communication.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.
