There is a security vulnerability in SSLv3 with the name "POODLE" that can affect Thunderstone Search Appliances as well as any browser or server using SSL protocols. See CVE-2014-3566.
If you're using https services on your Thunderstone Search appliance you should go to "HTTPS/SSL Protocols" under "System Wide Settings" and uncheck SSLv3 (and SSLv2 if it's not already unchecked). Make sure TLSv1 is checked. Then click "Update".
Disabling SSLv3 may prevent https access by MS IE 6.
Note that system level admin is done via https so, unless you've firewalled that, you're using https services.
