GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2017-17560 (GCVE-0-2017-17560)

Vulnerability from cvelistv5 – Published: 2017-12-12 18:00 – Updated: 2024-08-05 20:51
VLAI Shadowserver Previdian
Summary
An issue was discovered on Western Digital MyCloud PR4100 2.30.172 devices. The web administration component, /web/jquery/uploader/multi_uploadify.php, provides multipart upload functionality that is accessible without authentication and can be used to place a file anywhere on the device's file system. This allows an attacker the ability to upload a PHP shell onto the device and obtain arbitrary code execution as root.
