The target is running at least one instance of IlohaMail version 0.8.6. This version may contain flaws in the spell check and GnuPG features that allow an authenticated attacker to run arbitrary commands with the privileges of the web user simply by enclosing them in backticks when spell checking or sending a message. ***** OVS has determined the vulnerability exists on the target ***** simply by looking at the version number of IlohaMail ***** installed there.

Upgrade to IlohaMail version 0.8.7 or later or disable spell check and GPG features (see conf/conf.inc).
