Zoom has addressed four security vulnerabilities that could enable remote code execution, crash other attendees' clients, or access sensitive files This article explores zoom addressed security. . It affects Zoom's annotation engine and can be exploited without requiring the victim to click a link, accept a prompt, download a file, or take any visible action beyond joining a meeting.
A remote user can exploit this vulnerability by accessing the network to execute malicious code on another participant’s system during a screen-sharing session. Due to unreliable client confirmation of incoming values fitting into destination buffers, malicious participants could exploit this flaw by overwriting adjacent memory, leading to arbitrary code execution and altering application control flow.
This risk extends beyond just that action: a successful remote code execution vulnerability can be exploited for malware deployment, data collection, persistence, or access to device resources through the compromised Zoom client. Users of VDI environments should upgrade their software to the latest versions: Zoom Workplace VDI Client 7.0.11 or 6.6.16, and Zoom VDI Plugin 7.0.11 or 6.6.15, depending on their supported branch. Administrators should centrally deploy updated Zoom packages, enforce minimum versions using endpoint management tools, update gold images, and investigate any unusual processes launched by Zoom clients.
