Summary
The remote server is running at least one instance of IMP whose version number is between 3.0 and 3.2.1 inclusive. Such versions are vulnerable to several cross-scripting attacks whereby an attacker can cause a victim to unknowingly run arbitrary Javascript code simply by reading an HTML message from the attacker.
Announcements of the vulnerabilities can be found at :

Note : OVS has determined the vulnerability exists on the target simply by looking at the version number of IMP installed there. If the installation has already been patched, consider this a false positive.
Solution
Upgrade to IMP version 3.2.2 or later or apply patches found in the announcements to imp/lib/MIME/Viewer/html.php.
