Mitel updated their Security Advisory on this late last night, MiCollab 9.x is impacted. They've got a patch published, apply using a curl command to download and run the patch shell script, but it requires a reboot of the MiCollab server. I've got about 70 systems that need to be patched, sending out notifications to my customers and basically telling them the window we're applying the patch in and to call us if they need to schedule outside of our window. You will want to jump on this ASAP, the vulnerability is actively being exploited to deploy ransomware.
