SfB 2015 Server Security Update – July 2020

Today we see one of a (thankfully) rare occurrence – a security update for Skype for Business Server (both 2015 and 2019).

SfBS RGS lets you spoof a SIP Domain

  A long-standing bug in Skype for Business’s Response Group Service (“RGS”) is that it doesn’t validate the line URI when you create a new Workflow. This means it won’t err out if you chose a number that’s already in use elsewhere, and the upshot is that neither the existing user nor the response group …

Cscp logs Event 35009 – “Authorization Failed”

My colleagues and I recently encountered an intermittent problem with the CSCP reporting “Authorization Failed” when you tried to sign in. This was a Skype for Business 2015 Enterprise Edition pool, and so it didn’t take long to localise the issue to just one Front-End server. Each failed attempt dropped an instance of event 35009 …
