CVE-2025-14693

Physical file access via USB symlink following

Published Dec 15, 2025 · Updated Dec 15, 2025

Symlink following in the USB Handler of UGREEN DH2100+ 5.0 through 5.3.0 allows physically proximate attackers to access unintended files. Published materials do not identify the affected function or explain how the handler accepts and resolves a crafted symbolic link. Exploitation requires direct physical access and high privileges; the record reports no network path and does not distinguish file reads from writes.
