CVE-2020-29014Network attack vector

Authenticated service hang via command-shell race

Published Jul 9, 2021 · Updated Oct 25, 2024

A race condition in the FortiSandbox command shell before 3.2.2 allows remote authenticated users to make the appliance unresponsive. The shell permits concurrent command sequences to access a shared resource without proper synchronization. A valid authenticated shell session and a specifically orchestrated command sequence are required, and successful exploitation interrupts service rather than disclosing or altering data.
