vCenter Service Access Lock Down Due To Severe Vulnerability - No Impact

Incident Report for University of Waterloo

Monitoring

Due to a severe vulnerability announced by VMware today, IST has planned to lock down access to vCenter server to whitelisted hosts/subnets only. We will re-evaluate this remediation once we have the affected systems patched.

Running VMs and hosted services remain unaffected.
For VM admins who require access to vCenter Web Interface to manage your VM, IST is currently in process of setting up an RDApp that you can access later, https://vdiapps.uwaterloo.ca/RDweb

Please let us know if you have any questions or concerns. If you have an emergency need to access the vCenter, please reach out to my email directly at tony.zhu@uwaterloo.ca
