CVE-2018-18566
The SIP service in Polycom VVX 500 and 601 devices 5.8.0.12848 and earlier allow remote attackers to obtain sensitive phone configuration information by leveraging use with an on-premise installation with Skype for Business.
Does this matter?
Lower severity and a low EPSS score (2.75%). Track it; it rarely justifies an emergency change on its own.
