CVE-2022-23346Public exploitNetwork attack vector

Remote code execution via unrestricted file upload

Published Mar 21, 2022 · Updated Jul 9, 2026

Improper access control in BigAnt Server 5.6.06 allows remote attackers to execute code via malicious file uploads. The Cloud Disk and Broadcast upload paths accept executable PHP extensions, disclose stored paths through sharing or page source, and permit retrieval without effective authorization. An attacker able to reach those features can run the uploaded script as the server system account; the public proof of concept does not establish exploitation in the wild.
