CVE-2020-3982 – VMware Workstation BDOOR_CMD_PATCH_ACPI_TABLES Time-Of-Check Time-Of-Use Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3982
VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202008101-SG, 6.5 before ESXi650-202007101-SG), Workstation (15.x), Fusion (11.x before 11.5.6) contain an out-of-bounds write vulnerability due to a time-of-check time-of-use issue in ACPI device. A malicious actor with administrative access to a virtual machine may be able to exploit this vulnerability to crash the virtual machine's vmx process or corrupt hypervisor's memory heap. VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.1-0.0.16850804, versiones 6.7 anteriores a ESXi670-202008101-SG, versiones 6.5 anteriores a ESXi650-202007101-SG), Workstation (versiones 15.x), Fusion (versiones 11.x anteriores a de 11.5.6), contienen una vulnerabilidad de escritura fuera de límites debido a un problema time-of-check time-of-use en el dispositivo ACPI. Un actor malicioso con acceso administrativo a una máquina virtual puede ser capaz de explotar esta vulnerabilidad para bloquear el proceso vmx de la máquina virtual o corromper la pila de la memoria del hipervisor This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the implementation of the BDOOR_CMD_PATCH_ACPI_TABLES command. • https://www.vmware.com/security/advisories/VMSA-2020-0023.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-787: Out-of-bounds Write •
