**Description**
The issue is related to insufficient input validation, which could allow a remote attacker to execute arbitrary code. Specifically, the network proxy page on the web portal for certain Zoom products fails to validate input sent in requests to set the network proxy password, potentially leading to remote command injection by a web portal administrator.
