We outline details about Foreshadow vulnerabilities, including security flaws identified, what we're doing to combat them, risk level and recommendations.

Updated - 20th September 2018

Overview of the Foreshadow vulnerabilities

Three related security flaws have been identified which affect Intel processors. These are known as Foreshadow (CVE-2018-3615) and Foreshadow-NG (CVE-2018-3620, CVE-2018-3646)

Risk level

The risk of exploitation in a Speakerbus solution is assessed as low.

Speakerbus confirm that any Server products could have some level of exposure to the vulnerabilities.

Those installed on Windows Servers are:

  • iManager Centralised Management System (iCMS),
  • iManager Call Data Server (iCDS),
  • SB 534 GA Server and System Controllers
  • Voice Conference Manager (VCM) products.
  • ARIA iManager Web Server (iWS)

Tests and recommendations 

Speakerbus have tested the Microsoft patches for Windows Server 2008 (KB4343900) and Windows Server 2012 (KB4343898) for all the relevant above-listed products. We recommend that they are applied to ensure the continued security of the servers.

Those installed on CentOS / Red Hat Servers are:

  • iManager Communication Server (iCS)
  • iManager Gateway Server (iGS)
  • ARIA iManager CloudBase (iCB)

We are currently updating the iCS, iGS and iCB to remove this vulnerability in our upcoming software releases to be made available during Q4 2018.
