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.
