CVE-2024-38909Network attack vector

Unauthenticated code execution via unchecked cross-directory copy

Published Jul 30, 2024 · Updated Jul 9, 2026

Improper access control in Studio 42 elFinder 2.1.64 allows remote attackers to execute code by copying a forbidden file type. The Copy/Paste folders function copies files between server directories without reapplying the destination's extension restrictions. An unauthenticated, network-reachable connector with writable source and destination directories permits secret exposure or server-side code execution.
