CVE-2018-25412Public exploitNetwork attack vectorHinoki check available

Remote code execution via unrestricted PHP upload

Published May 30, 2026 · Updated May 30, 2026

Arbitrary file upload in Delta Sql 1.8.2 allows remote attackers to execute PHP code by posting a crafted file to docs_upload.php. The handler accepts the fileToUpload filename and content without restricting executable extensions, then stores the file in the web-accessible upload directory. No login or user interaction is required; requesting the uploaded PHP file executes its contents with the web server process privileges.
