CVE-2022-28945Public exploitNetwork attack vector

Unauthenticated file writes via unchecked ZIP paths

Published May 31, 2022 · Updated Jul 9, 2026

Path traversal in Webbank WeCube 3.2.2 allows remote attackers to write outside the extraction directory via a crafted ZIP file. The unzipLocalFile method concatenates each ZipEntry name directly with the destination path without rejecting ../ segments or verifying the canonical path. No authentication or user interaction is required, and exploitation creates or appends data to files writable by the WeCube process.
