Recently, VMware has released a security bulletin about VMware Tools to which hackers can gain access. Only specific versions of VMware tools are targetted and some Windows and MacOS systems are affected. You should, however, make sure to check whether you're affected and then patch those VMware Tools to the latest version, which has recently been released.
Running the latest version of VMware Tools is crucial to ensure the security of your virtual infrastructure. As you all already know, VMware Tools is a suite of utilities that enhances the performance and management of virtual machines. It is essential to keep these tools up-to-date to prevent security breaches and vulnerabilities.
VMware Tools contains a local privilege escalation vulnerability. VMware has evaluated the severity of this issue to be in the Important severity range with a maximum CVSSv3 base score of 7.8. A malicious actor with local user access to a guest virtual machine may elevate privileges within the virtual machine and then initiate some actions.
The latest version of VMware Tools is available here:
To check your version of VMware tools you can do it in several ways, via vSphere client, via RVTools or another third-party app.
The latest version of VMware Tools provides several security features that can help protect your virtual machines from attacks. For instance, it offers UEFI Secure Boot, Virtualization-based Security, vTPM, encrypted vMotion, VM encryption, vSAN encryption, and more. These features can help improve the security of guest operating systems.
It is also important to keep track of updates for dormant virtual machines that are powered off because it can be easy to overlook them. Ensure that anti-virus software, anti-spyware, intrusion detection, and other protection are enabled for every virtual machine in your virtual infrastructure.
In addition, it is recommended to eliminate unnecessary services and ports to strengthen the security of servers. Updating with the latest service packs and patches, as well as the latest antivirus software versions, is also crucial. Make sure you enable default server firewalls to add an extra layer of protection.
