Vmware Esxi

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process.

VMware ESXi contains an arbitrary write vulnerability. A malicious actor with privileges within the VMX process may trigger an arbitrary kernel write leading to an escape of the sandbox.

VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

VMware ESXi contains an out-of-bounds read vulnerability. A
malicious actor with local administrative privileges on a virtual machine with an existing snapshot may trigger an out-of-bounds read leading to a denial-of-service condition of the host.

VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management https://blogs.vmware.com/vsphere/2012/09/joining-vsphere-hosts-to-active-directory.html by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.

The storage controllers on VMware ESXi, Workstation, and Fusion have out-of-bounds read/write vulnerability. A malicious actor with access to a virtual machine with storage controllers enabled may exploit this issue to create a denial of service condition or execute code on the hypervisor from a virtual machine in conjunction with other issues.

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability in the UHCI USB controller. A malicious actor with administrative access to a virtual machine may be able to exploit this issue to leak memory from the vmx process. Â

VMware ESXi contains an out-of-bounds write vulnerability. A malicious actor with privileges within the VMX process may trigger an out-of-bounds write leading to an escape of the sandbox.

VMware ESXi, Workstation, and Fusion contain a use-after-free vulnerability in the UHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

VMware ESXi, Workstation, and Fusion contain a use-after-free vulnerability in the XHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a significant amplification factor.

VMware ESXi, Workstation, and Fusion contain a heap out-of-bounds write vulnerability in the USB 2.0 controller (EHCI). A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

VMware ESXi contains a heap-overflow vulnerability. A malicious local actor with restricted privileges within a sandbox process may exploit this issue to achieve a partial information disclosure.

VMware ESXi contains a memory corruption vulnerability that exists in the way it handles a network socket. A malicious actor with local access to ESXi may exploit this issue to corrupt memory leading to an escape of the ESXi sandbox.

VMware ESXi contains a null-pointer deference vulnerability. A malicious actor with privileges within the VMX process only, may create a denial of service condition on the host.

Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.

Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

ESXi contains a slow HTTP POST denial-of-service vulnerability in rhttpproxy. A malicious actor with network access to ESXi may exploit this issue to create a denial-of-service condition by overwhelming rhttpproxy service with multiple requests.

VMware ESXi contains a TOCTOU (Time-of-check Time-of-use) vulnerability that exists in the way temporary files are handled. A malicious actor with access to settingsd, may exploit this issue to escalate their privileges by writing arbitrary files.

VMware ESXi contains an unauthorized access vulnerability due to VMX having access to settingsd authorization tickets. A malicious actor with privileges within the VMX process only, may be able to access settingsd service running as a high privileged user.

VMware ESXi, Workstation, and Fusion contain a double-fetch vulnerability in the UHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

VMware ESXi, Workstation, and Fusion contain a use-after-free vulnerability in the XHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

VMware ESXi (7.0, 6.7 before ESXi670-202111101-SG and 6.5 before ESXi650-202110101-SG), VMware Workstation (16.2.0) and VMware Fusion (12.2.0) contains a heap-overflow vulnerability in CD-ROM device emulation. A malicious actor with access to a virtual machine with CD-ROM device emulation may be able to exploit this vulnerability in conjunction with other issues to execute code on the hypervisor from a virtual machine.
