DLL hijacking in the WD Discovery Installer in Western Digital WD Discovery 5.2.730 on Windows allows a local attacker to execute arbitrary code via placement of a crafted dll in the installer's search path.

WD Discovery versions prior to 5.0.589 contain a misconfiguration in the Node.js environment settings that could allow code execution by utilizing the 'ELECTRONRUNASNODE' environment variable. Any malicious application operating with standard user permissions can exploit this vulnerability, enabling code execution within WD Discovery application's context. WD Discovery version 5.0.589 addresses this issue by disabling certain features and fuses in Electron. The attack vector for this issue requires the victim to have the WD Discovery app installed on their device.

In Western Digital WD Discovery before 4.0.251.0, a malicious application running with standard user permissions could potentially execute code in the application's process through library injection by using DYLD environment variables.

The Western Digital WD Discovery application before 3.8.229 for MyCloud Home on Windows and macOS is vulnerable to CSRF, with impacts such as stealing data, modifying disk contents, or exhausting disk space.
