AI-suggested
If you cannot patch yet, organizations should implement strict local access controls to limit the number of users with authenticated access to affected Zoom Workplace clients. Employ endpoint protection solutions that monitor for unusual privilege escalation attempts and enforce application whitelisting to prevent unauthorized modifications to Zoom client files. Regularly audit user permissions and remove unnecessary local accounts or privileges. Network segmentation can reduce the risk of lateral movement if an escalation occurs. Enable detailed logging and monitoring on endpoints to detect suspicious activities related to Zoom Workplace processes. Educate users about the risks of local privilege escalation and encourage reporting of unusual system behavior. Additionally, consider using application sandboxing or containerization to isolate Zoom Workplace processes, limiting the impact of potential exploits.
Description
Improper Check of minimum version in update functionality of certain Zoom Clients for Windows may allow an authenticated user to conduct an escalation of privilege via local access.
