Zoom Client < 4.6.10 Weak Encryption

high Nessus Plugin ID 140133

Language:

Synopsis

The remote host has an application installed that is affected by a weak encryption vulnerability.

Description

The version of the Zoom Client installed on the remote host is prior to 4.6.10. It is, therefore, affected by a weak encryption vulnerability. Zoom Client for Meetings through 4.6.9 uses the ECB mode of AES for video and audio encryption. Within a meeting, all participants use a single 128-bit key.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Zoom Client for Meetings 4.6.10 or later.
