The CVE-2022-31705 vulnerability (CVSSv3 base score of 9.3) is a heap out-of-bounds write issue in the USB 2.0 controller (EHCI).
“VMware ESXi, Workstation, and Fusion contain a heap out-of-bounds write vulnerability in the USB 2.0 controller (EHCI)” reads the advisory published by the virtualization giant. “A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine’s VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.”
The company also addressed a command injection and directory traversal security vulnerabilities, respectively tracked as CVE-2022-31702 and CVE-2022-31703, impacting the VMware vRealize Network Insight (vRNI) solution. Below are the details for the flaws:
- VMware vRealize Network Insight (vRNI) command injection vulnerability (CVE-2022-31702) – “vRealize Network Insight (vRNI) contains a command injection vulnerability present in the vRNI REST API.” states the advisory. “A malicious actor with network access to the vRNI REST API can execute commands without authentication.”
- VMware vRealize Network Insight (vRNI) contains a directory traversal vulnerability (CVE-2022-31703) – “vRealize Network Insight (vRNI) directory traversal vulnerability in vRNI REST API.” reads the advisory. “A malicious actor with network access to the vRNI REST API can read arbitrary files from the server.”
