Analysis Summary
CVE-2021-22050
Vmware ESXi is vulnerable to a denial of service, caused by a slow HTTP POST denial-of-service vulnerability in rhttpproxy. By overwhelming rhttpproxy service with multiple requests, an attacker could exploit this vulnerability to cause a denial of service.
CVE-2021-22043
VMware ESXi could allow a local authenticated attacker to gain elevated privileges on the system, caused by a TOCTOU (Time-of-check Time-of-use) vulnerability that exists in the way temporary files are handled. By writing arbitrary files, an attacker could exploit this vulnerability to escalate their privileges.
CVE-2021-22042
Vmware ESXi could allow a local authenticated attacker to gain access to the system, caused by VMX having access to settingsd authorization tickets. An attacker could exploit this vulnerability to access settingsd service running as a high privileged user.
CVE-2021-22041, CVE-2021-22040
Vmware ESXi, Workstation and Fusion could allow a local attacker to execute arbitrary code on the system, caused by a double-fetch vulnerability in the UHCI USB controller. An attacker could exploit this vulnerability to execute code as the virtual machine’s VMX process running on the host.
