VMware has released a new security advisory VMSA-2020-0023: VMware ESXi, Workstation, Fusion, NSX-T, and vCenter Server Appliance updates address multiple security vulnerabilities. VMware Cloud Foundation is also an impacted product.
ESXi OpenSLP remote code execution vulnerability (CVE-2020-3992)
OpenSLP as used in ESXi has a use-after-free issue. A malicious actor residing in the management network who has access to port 427 on an ESXi machine may be able to trigger a use-after-free in the OpenSLP service resulting in remote code execution. If you can’t upgrade to the fixed version, as a workaround you can disable CIM server, documented in VMware KB 76372.
