In Ubiquiti Networks EdgeSwitch X v1.1.0 and prior, an authenticated user can execute arbitrary shell commands over the SSH interface bypassing the CLI interface, which allow them to escalate privileges to root.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
