CVE-2025-30240
Arbitrary File Read via Improper Symlink Handling in USB HTTPS Access Path in multiple TP-Link Aginet Devices
Overview
Description
The affected TP-Link Aginet devices do not properly validate symbolic links created on external USB storage devices. By placing a crafted symbolic link on supported storage media, an attacker may cause the system to resolve the link. Successful exploitation may allow unauthorized read access to sensitive files within the device filesystem.
