  1. LowCVSS 2.7 EPSS 0.69% CISA KEV added 2026-10-28 Exploited in the wild

    VMware ESX contains an insufficient logging vulnerability. A malicious administrator could exploit this issue to perform certain operations without them being logged.

  2. HighCVSS 7.6 EPSS 0.43%

    VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host proce...

  3. CriticalCVSS 9.3 EPSS 0.19%

    VMware ESX contains an out-of-bounds write vulnerability in the VMXNET3 virtual network adapter. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Non VMXNET3 virtua...

  4. CriticalCVSS 9.8 EPSS 99.9% CISA KEV added 2022-01-28 Exploited in the wild Public exploit PoC

    GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vect...

  5. CriticalCVSS 9.8 EPSS 100.0% CISA KEV added 2022-01-28 Exploited in the wild Framework module Public exploit PoC

    GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the...

  6. LowCVSS 3.3 EPSS 0.68%

    VMware Workstation 9.x before 9.0.1, VMware Player 5.x before 5.0.1, VMware Fusion 5.x before 5.0.1, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1 allow guest OS users to cause a denial of service (VMX process disruption) by using an invalid port.

  7. MediumCVSS 4.4 EPSS 0.35%

    VMware ESXi 4.0 through 5.5 and ESX 4.0 and 4.1 allow local users to read or modify arbitrary files by leveraging the Virtual Machine Power User or Resource Pool Administrator role for a vCenter Server Add Existing Disk action with a (1) -flat, (2) -rdm, or (3) -rdmp filename.

  8. HighCVSS 7.9 EPSS 0.51%

  9. MediumCVSS 4.3 EPSS 1.1%

    VMware ESXi 4.0 through 5.1, and ESX 4.0 and 4.1, does not properly implement the Network File Copy (NFC) protocol, which allows man-in-the-middle attackers to cause a denial of service (unhandled exception and application crash) by modifying the client-server data stream.

  10. HighCVSS 10.0 EPSS 2.8%

    VMware vCenter Server 4.0 before Update 4b and 4.1 before Update 3a, VMware VirtualCenter 2.5, VMware vSphere Client 4.0 before Update 4b and 4.1 before Update 3a, VMware VI-Client 2.5, VMware ESXi 3.5 through 4.1, and VMware ESX 3.5 through 4.1 do not properly implement the mana...
