CVE-2025-66945Public exploitNetwork attack vector

Authenticated file overwrite via unchecked ZIP entry paths

Published Mar 3, 2026 · Updated Mar 3, 2026

Path traversal in Zdir Pro 4.1.1 through 4.6.2 allows remote authenticated users to overwrite files via a crafted ZIP archive. The zdir/controller.unzip function joins each untrusted ZIP entry name to the extraction path, then creates directories and files without verifying that the result remains inside the target directory. Exploitation requires access to upload and extract archives; escaped writes can overwrite application files and enable code execution.
