## Technical details

The vulnerability is a classic zip slip (path traversal) flaw in the FileOperation.unzip() function accessed via the /networkDisk/unzipFile endpoint. By crafting a malicious ZIP archive with path traversal sequences (e.g., "../../../") in filenames, an attacker can write files outside the intended extraction directory. The attack requires network access and does not require authentication. An attacker can achieve arbitrary file write on the server, potentially leading to remote code execution. The vendor was notified early but did not respond or provide a patch.
