8) Stack-based buffer overflow (CVE-ID: CVE-2022-33183)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the "firmwaredownload" and "diagshow" commands. A remote user can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
