CVE-2018-18567
AudioCodes 440HD and 450HD devices 3.1.2.89 and earlier allows man-in-the-middle attackers to obtain sensitive credential information by leveraging failure to validate X.509 certificates when used with an on-premise installation with Skype for Business.
Does this matter?
Lower severity and a low EPSS score (1.18%). Track it; it rarely justifies an emergency change on its own.
