Zoom Client < 4.6.10 Windows Installer Vulnerability (ZSB-20001) - Windows

Zoom Client is prone to a vulnerability in the Windows installer.

A vulnerability in how the Zoom Windows installer handles junctions when deleting files could allow a local Windows user to delete files otherwise not deletable by the user. The vulnerability is due to insufficient checking for junctions in the directory from which the installer deletes files, which is writable by standard users. A malicious local user could exploit this vulnerability by creating a junction in the affected directory that points to protected system files or other files to which the user does not have permissions. Upon running the Zoom Windows installer with elevated permissions, as is the case when it is run through managed deployment software, those files would get deleted from the system.

Zoom Client versions prior to 4.6.10 on Windows.

Checks if a vulnerable version is present on the target host.

Update to version 4.6.10 or later.
