CVE-2020-3969 – VMware Workstation SVGA3D Command Heap Overflow Privilege Escalation Vulnerability

https://notcve.org/view.php?id=CVE-2020-3969

VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.5), and Fusion (11.x before 11.5.5) contain an off-by-one heap-overflow vulnerability in the SVGA device. A malicious actor with local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible. VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.0-1.20.16321839, versiones 6.7 anteriores a ESXi670-202004101-SG y versiones 6.5 anteriores a ESXi650-202005401-SG), Workstation (versiones 15.x anteriores a 15.5.5) y Fusion (versiones 11.x anteriores a 11.5. 5), contienen una vulnerabilidad de desbordamiento de pila por un paso en el dispositivo SVGA. Un actor malicioso con acceso local a una máquina virtual con gráficos 3D habilitados puede ser capaz de explotar esta vulnerabilidad para ejecutar código en el hipervisor desde una máquina virtual. • https://www.vmware.com/security/advisories/VMSA-2020-0015.html https://www.zerodayinitiative.com/advisories/ZDI-20-786 • CWE-193: Off-by-one Error •

CVE-2020-3958

https://notcve.org/view.php?id=CVE-2020-3958

VMware ESXi (6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), VMware Workstation (15.x before 15.5.2) and VMware Fusion (11.x before 11.5.2) contain a denial-of-service vulnerability in the shader functionality. Successful exploitation of this issue may allow attackers with non-administrative access to a virtual machine to crash the virtual machine's vmx process leading to a denial of service condition. VMware ESXi (versiones 6.7 anteriores a ESXi670-202004101-SG y versiones 6.5 anteriores a ESXi650-202005401-SG), VMware Workstation (versiones 15.x anteriores a 15.5.2) y VMware Fusion (versiones 11.x anteriores a 11.5.2), contienen una vulnerabilidad de denegación de servicio en la funcionalidad shader. Una explotación con éxito de este problema puede permitir a atacantes con acceso no administrativo a una máquina virtual bloquear el proceso vmx de la máquina virtual, conllevando a una condición de denegación de servicio. • https://www.talosintelligence.com/vulnerability_reports/TALOS-2019-0957 https://www.vmware.com/security/advisories/VMSA-2020-0011.html • CWE-617: Reachable Assertion •

CVE-2020-3957

https://notcve.org/view.php?id=CVE-2020-3957

VMware Fusion (11.x before 11.5.5), VMware Remote Console for Mac (11.x and prior) and VMware Horizon Client for Mac (5.x and prior) contain a local privilege escalation vulnerability due to a Time-of-check Time-of-use (TOCTOU) issue in the service opener. Successful exploitation of this issue may allow attackers with normal user privileges to escalate their privileges to root on the system where Fusion, VMRC and Horizon Client are installed. VMware Fusion (versiones 11.x anteriores a 11.5.5), VMware Remote Console para Mac (versiones anteriores a 11.x ) y VMware Horizon Client para Mac (versiones anteriores a 5.x), contienen una vulnerabilidad de escalada de privilegios local debido a un problema de tipo Time-of-check Time-of-use (TOCTOU) en el abridor de servicio. Una explotación con éxito de este problema puede permitir a atacantes con privilegios de usuario normal escalar sus privilegios a root en el sistema donde están instalados Fusion, VMRC y Horizon Client. • https://www.vmware.com/security/advisories/VMSA-2020-0011.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

CVE-2020-3950 – VMware Multiple Products Privilege Escalation Vulnerability

https://notcve.org/view.php?id=CVE-2020-3950

VMware Fusion (11.x before 11.5.2), VMware Remote Console for Mac (11.x and prior before 11.0.1) and Horizon Client for Mac (5.x and prior before 5.4.0) contain a privilege escalation vulnerability due to improper use of setuid binaries. Successful exploitation of this issue may allow attackers with normal user privileges to escalate their privileges to root on the system where Fusion, VMRC or Horizon Client is installed. VMware Fusion (versiones 11.x anteriores a 11.5.2), VMware Remote Console for Mac (versiones 11.x y anteriores a 11.0.1) y Horizon Client for Mac (versión 5.x y anteriores a 5.4.0), contienen una vulnerabilidad de escalada de privilegios debido al uso inapropiado de binarios setuid. Una explotación con éxito de este problema puede permitir a atacantes con privilegios de usuario normal escalar sus privilegios a root sobre el sistema donde Fusion, VMRC o Horizon Client es instalado. VMware Fusion version 11.5.2 suffers from a privilege escalation vulnerability. • https://www.exploit-db.com/exploits/48235 https://www.exploit-db.com/exploits/48337 http://packetstormsecurity.com/files/156843/VMware-Fusion-11.5.2-Privilege-Escalation.html http://packetstormsecurity.com/files/157079/VMware-Fusion-USB-Arbitrator-Setuid-Privilege-Escalation.html https://www.vmware.com/security/advisories/VMSA-2020-0005.html • CWE-269: Improper Privilege Management •

CVE-2020-3948 – VMware Workstation Virtual Printer External Control of File Name Privilege Escalation Vulnerability

https://notcve.org/view.php?id=CVE-2020-3948

Linux Guest VMs running on VMware Workstation (15.x before 15.5.2) and Fusion (11.x before 11.5.2) contain a local privilege escalation vulnerability due to improper file permissions in Cortado Thinprint. Local attackers with non-administrative access to a Linux guest VM with virtual printing enabled may exploit this issue to elevate their privileges to root on the same guest VM. Linux Guest VMs ejecutado en VMware Workstation (versiones 15.x anteriores a 15.5.2) y Fusion (versiones 11.x anteriores a 11.5.2), contienen una vulnerabilidad de escalada de privilegios locales debido a permisos de archivo inapropiados en Cortado Thinprint. Los atacantes locales con acceso no administrativo a una Máquina Virtual invitada de Linux con impresión virtual habilitada pueden explotar este problema para elevar sus privilegios para rootear en la misma máquina virtual invitada. This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. • https://www.vmware.com/security/advisories/VMSA-2020-0004.html • CWE-732: Incorrect Permission Assignment for Critical Resource •
