This can cause the application to execute a SQL query or get redirected to a malicious site. Access, Identity Manager and vRealize Automation contain a cross site scripting vulnerability. A malicious actor can inject script into a web application to steal data or execute arbitrary script.
If you are a vSphere administrator and want to protect your infrastructure, there is no better option than upgrading your vSphere hosts to the latest version. Whether it’s from the performance perspective, the stability of the platform or the features offered with the latest release, upgrading is always the best option.

This article only focuses on protecting vSphere administrators. You should also be aware that other VMware products, such as VMware Fusion and vRealize Automation, are not mentioned in this article.
VMware vSphere: The Basics
Virtualization is the process of creating a virtual machine (VM) on top of a physical machine. VMs allow for multiple operating systems, applications and services to run simultaneously on one physical machine. The benefits of implementing virtual machines are vast and can include:
- Increased flexibility - Reduced hardware costs - Improved security
Many organizations use VMware vSphere because it offers many advantages over other technologies due to its ability to consolidate workloads across many servers.
vSphere Upgrade Guide
1. Click on the “Edit” tab in the top menu bar of the VMware vSphere Web Client, then select “Settings”.
2. Navigate to “Update Manager”, then click on “Upgrade Status”. You will see your current build, which will be shown in a green field and show if there are any known issues with upgrading.
3. Select the build you want to upgrade from and click on the upgrade button on the right-hand side of the page. Upgrade will begin immediately in the background while you continue working in your environment.
Upgrade vSphere hosts to the latest version
If you are a virtual machine administrator, the best thing you can do for your virtual machines is to upgrade your hosts to the latest version. This ensures that you have more resources and better performance for your VMs. With the latest release, you can also take advantage of new features that might not be available on older versions.
If you are a vSphere administrator and want to protect your infrastructure, it is always a better option to upgrade your hosts to the latest version. There are many reasons why this is true, but one of them is that with new releases comes new security fixes.
For vSphere Admins
With the latest release of vSphere, you can perform host upgrade with two ways: Host profiles and scripted upgrade.
If you have a script that is already in place, then you can use the scripted upgrade method. If not, then you can use host profiles.
The following are some of the advantages of using host profiles as they are easier to manage and maintain than scripted upgrade.
- You don’t need to install or download scripts on each individual host.
- Host profiles are easy to create and deploy which should be done during a maintenance window when no hosts are running any workloads.
- After deployment, updates will happen automatically at a certain time interval for automated deployments which saves time.
- The script will only be applied on hosts that are currently running workloads which saves resources on unnecessary virtual machine hardware upgrades as well as virtual machine hardware reclamation/recycling.
