CVE-2012-10016Network attack vector

Server file disclosure via download path traversal

Published Oct 16, 2023 · Updated Sep 16, 2024

Path traversal in Halulu Simple Download Button Shortcode 1.0 allows remote attackers to read server files through its download handler. The simple-download-button_dl.php script concatenates the unvalidated file query parameter with the configured download directory before checking the resulting path. No authentication is required; traversal outside the intended directory exposes files readable by the web server account, without altering files or interrupting service.
