CVE-2023-28603

Unauthorized file deletion via attacker-controlled paths

Published Jun 13, 2023 · Updated Jan 2, 2025

Improper access control in the Zoom VDI client installer before 5.14.0 allows local users to delete files without permission. Zoom identifies external control of a file name or path but has not published the affected installer locus or how attacker-controlled paths reach deletion. Exploitation requires low-privileged local access and no user interaction; the bounded consequence is unauthorized file deletion on the Windows host.
