Additional Advisory Data
Workarounds
CNA: InterSystems recommends users configure IRIS superserver to require SSL/TLS: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=ROARS_gsecuring_checklist Note that there are three settings: "Disabled", which means that client communications do not use TLS. "Enabled", which means that client communications may use TLS (but they also may not) and "Required", which forces all client communications to use TLS. InterSystems documentation explains how to configure the server to require TLS: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GSA_manage_superserver For more information about how to configure a system to mitigate this vulnerability, contact InterSystems at their world wide response center: https://wrc.intersystems.com (login required)
