In VMware ESXi (6.7 before ESXi670-201908101-SG, 6.5 before ESXi650-202007101-SG), Workstation (15.x before 15.1.0), Fusion (11.x before 11.1.0), the VMCI host drivers used by VMware hypervisors contain a memory leak vulnerability. A malicious actor with access to a virtual machine may be able to trigger a memory leak issue resulting in memory resource exhaustion on the hypervisor if the attack is sustained for extended periods of time. En VMware ESXi (versiones 6.7 anteriores a ESXi670-201908101-SG, versiones 6.5 anteriores a ESXi650-202007101-SG), Workstation (versiones 15.x anteriores a 15.1.0), Fusion (versiones 11.x anteriores a 11.1.0), los controladores del host VMCI utilizados por los hipervisores de VMware contienen una vulnerabilidad de filtrado de memoria. Un actor malicioso con acceso a una máquina virtual puede desencadenar un problema de filtrado de memoria que resulte en el agotamiento de los recursos de memoria en el hipervisor si el ataque se mantiene durante períodos prolongados • https://www.vmware.com/security/advisories/VMSA-2020-0023.html • CWE-401: Missing Release of Memory after Effective Lifetime •

VMware vCenter Server (6.7 before 6.7u3, 6.6 before 6.5u3k) contains a session hijack vulnerability in the vCenter Server Appliance Management Interface update function due to a lack of certificate validation. A malicious actor with network positioning between vCenter Server and an update repository may be able to perform a session hijack when the vCenter Server Appliance Management Interface is used to download vCenter updates. VMware vCenter Server (versiones 6.7 anteriores a 6.7u3, versiones 6.6 anteriores a 6.5u3k), contiene una vulnerabilidad de secuestro de sesión en la función de actualización de la vCenter Server Appliance Management Interface debido a la falta de comprobación del certificado. Un actor malicioso con posicionamiento de red entre vCenter Server y un repositorio de actualizaciones puede ser capaz de realizar un secuestro de sesión cuando la vCenter Server Appliance Management Interface es usado para descargar actualizaciones de vCenter • https://www.vmware.com/security/advisories/VMSA-2020-0023.html • CWE-295: Improper Certificate Validation •

VMware NSX-T (3.x before 3.0.2, 2.5.x before 2.5.2.2.0) contains a security vulnerability that exists in the way it allows a KVM host to download and install packages from NSX manager. A malicious actor with MITM positioning may be able to exploit this issue to compromise the transport node. VMware NSX-T (versiones 3.x anteriores 3.0.2, versiones 2.5.x anteriores a 2.5.2.2.0), contiene una vulnerabilidad de seguridad que se presenta en la manera en que permite que un host KVM descargue e instale paquetes desde el administrador de NSX. Un actor malicioso con posicionamiento MITM puede ser capaz de explotar este problema para comprometer el nodo de transporte • https://www.vmware.com/security/advisories/VMSA-2020-0023.html •
CVSS: 10.0EPSS: 44%CPEs: 224EXPL: 0CVE-2020-3992 – VMware ESXi OpenSLP Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2020-3992
OpenSLP as used in VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202010401-SG, 6.5 before ESXi650-202010401-SG) 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. OpenSLP como es usado en VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.1-0.0.16850804, versiones 6.7 anteriores a ESXi670-202010401-SG, versiones 6.5 anteriores a ESXi650-202010401-SG), presenta un problema de uso de la memoria previamente liberada. Un actor malicioso que reside en la red de administración y que tiene acceso al puerto 427 en una máquina ESXi puede desencadenar un uso de la memoria previamente liberada en el servicio OpenSLP resultando en una ejecución de código remota This vulnerability allows local attackers to escalate privileges on affected installations of VMware ESXi. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of SLP messages. • https://www.vmware.com/security/advisories/VMSA-2020-0023.html https://www.zerodayinitiative.com/advisories/ZDI-20-1377 https://www.zerodayinitiative.com/advisories/ZDI-20-1385 • CWE-416: Use After Free •

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 read 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 issue to leak memory from the vmx process. 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 (15.x), Fusion (11.x antes de 11.5.6), contienen una vulnerabilidad de lectura 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 este problema para filtrar la memoria del proceso vmx This vulnerability allows local attackers to disclose sensitive information 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-125: Out-of-bounds Read CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
