Vulnerabilities & Exploits

Zoom Workplace flaws could grant Windows host privileges

NCSC-NL says Zoom patched two vulnerabilities in Zoom Workplace for Windows, one scored 9.6 on the Common Vulnerability Scoring System (CVSS).

The client mishandles checks on where information comes from and whether input is valid, letting an attacker who can reach it over a network gain higher privileges without signing in. That could affect the Windows system’s integrity, not just a Zoom session.

For organizations running the Windows client, the exposure is on endpoints, not Zoom’s wider service. The advisory provides no evidence of exploitation or fixed-version details, so it does not establish whether any system was previously accessed.
