CVE-2024-30973Public exploitNetwork attack vector

Authenticated code execution via unchecked token authorization

Published May 6, 2024 · Updated Aug 9, 2024

Incorrect access control in V-SOL HG323AC-B firmware 2.0.08-210715 allows remote authenticated users to execute code via crafted POST requests. The formFirewall and formAcc handlers accept a low-privileged user's CSRF mask while performing administrator-only firewall and service changes. A low-privileged account can disable firewall rules, enable SSH, and then obtain remote command execution through the newly exposed service.
