CVE-2024-24202Network attack vector

Unauthenticated code execution via crafted text upload

Published Feb 8, 2024 · Updated Aug 19, 2024

Unrestricted file upload in ZenTao 18.10, ZenTao Biz 8.10, and ZenTao Max 4.10 allows remote attackers to execute arbitrary code. The /upgrade/control.php endpoint accepts a crafted .txt upload whose contents can execute as code; the exact validation failure is undisclosed. No authentication or user interaction is required, so a network-reachable deployment can be fully compromised.
