Avaya has patches for critical internet facing components for Remote Worker including ASBCE 8.1.3, AADS 8.1.4.1 (new binary), and Session Manager 8.1.3 (although I've asked about proof on this one).
I would not run remote worker without the patches in place. I have been seeing hacking attempts from Russia, the Ukraine, and Germany(a redirect from Russia) over the past 2 weeks. I expect US based hosted solution provider attacks are also happening. I would also strongly suggest eliminating any outbound internet capability from AADS and Session Manager at this time.
