The remote host is vulnerable to an HTML injection attack.
The target is running at least one instance of IlohaMail version 0.8.14 or earlier. The remote version of this software is vulnerable to an HTML injection attack. An attacker exploiting this flaw would need to convince a local user to open a malicious HTML email. Successful exploitation would result in the victim executing potentially damaging code and possibly theft of confidential, authentication-related data.
Upgrade to version 0.8.14-RC3 or higher.
