vCloud Director 9.5.0.3 (critical security update) - Update instructions

Security issue at hand:

VMware vCloud Director for Service Providers update resolves a Remote Session Hijack vulnerability in the Tenant and Provider Portals. Successful exploitation of this issue may allow a malicious actor to access the Tenant or Provider Portals by impersonating a currently logged in session.

Personal note / comment (I started to add this as I get often asked to evaluate the "real criticality/risk factor" by our strategic accounts):

This is a very critical issue which could directly affect customer/tenant data security, therefore I advice to give the test and upgrade procedure highest priority. Ensure this get's validated on test infrastructure before applied to production systems.



Release Notes: https://docs.vmware.com/en/vCloud-Director/9.5/rn/vCloud-Director-9503-for-Service-Providers-Release-Notes.html

Prerequisites for this update:

  • Read the Release Notes (above)
  • If you are already running vCloud Director 9.5 then no backend database service update (like from PostgreSQL 9.5 to 10) is required, if you need that please read my blog post on vCloud Director database upgrades.
