What is CVE-2021-22130?

A stack-based buffer overflow vulnerability exists in FortiProxy's command line interface (CLI) that affects several versions ranging from 1.0.0 to 2.0.1. This vulnerability allows an authenticated remote attacker to execute a Denial of Service (DoS) attack by inputting a large cpuset mask value into the diagnose sys cpuset command.
