![]() How do I fix those?ĮSXi is not Linux or UNIX and does not follow the permission models of those operating systems. My scanning tool discovered permission problems when scanning ESXi. VMware is committed to the security and stability of our products and customers, and if there are issues or concerns, please begin by opening a support case with VMware Global Support Services. ![]() If needed, a subsequent update to the product will be made available through the supported update mechanisms according to the response policy schedule.Ĭhanges made to file permissions or software components without the explicit guidance of VMware Global Support Services are not supported and may affect availability, serviceability, and supportability of your infrastructure. If a security or functional issue is reported to an external project VMware will assess its impact according to the VMware Security Response Policy. VMware tracks all software installed and in use as part of our products. This helps change managers and other organizational processes and staff understand that these appliances cannot be managed like other Linux systems. They are meant to be updated through the official APIs and interfaces.Īs such, it is better to treat the appliances more like network switch firmware, where the OS would be “VMware vCenter Server” instead of a Linux distribution. Altering them in any way outside the guidance of VMware Global Support Services is unsupported. While it is true that VMware virtual appliances are built on Linux, they are not general-purpose computing devices. What distribution of Linux do vCenter Server, SDDC Manager, and other appliances use? We strongly recommend SSH be left disabled, and that scanning tools examine the version information to determine if an update is available. ![]() ESXi is delivered and maintained as a single software image, similar to how a network switch firmware is delivered, and altering permissions or software inside that image may affect availability and support. There are no customer-serviceable or replaceable components inside ESXi. Neither are intended to be operational on the host. ESXi ships with SSH & the ESXi Shell disabled and off and raises alarms in vCenter Server if it is enabled and running. SSH and command shells (ESXi Shell) on vSphere components, like ESXi and vCenter Server, are maintenance & support tools designed for use only in temporary circumstances, at the guidance and instruction of VMware Global Support Services (GSS) staff. What is the best way to scan ESXi via SSH? Scanning VMware ESXi as a Linux or UNIX host will, at best, result in false positives and lost staff time interpreting the false positives. If your tool does not specifically support VMware vSphere components, you should avoid using it on your environment or use network-based scanning only. VMware ESXi is its own operating system and is neither Linux nor UNIX. My scanning tool is asking me whether ESXi is Linux or UNIX. We do recommend choosing a solution that specifically lists vSphere as a supported scanning target because it shows that the maker of the tool understands how vSphere is delivered. While we do not support scanning tools directly, we do support use of approved APIs and clients. VMware cannot make a recommendation for a particular scanning tool. If we still want to scan vCenter Server and/or ESXi via SSH, what's the best way?Ĭan VMware recommend a vulnerability scanning tool?.My compliance folks are insisting that they be granted SSH access to vSphere.Are there default accounts created on vCenter Server or ESXi?.Is there a way to limit users logging in to ESXi?.My scanning tool discovered issues with TLS.Are there any problems with network-based scanning?.If I shouldn’t use SSH how will I configure my ESXi host?.My scanning tool discovered a vulnerability in an appliance component, and I replaced the package with one from another Linux distribution. ![]()
