Does this matter?

Lower severity and a low EPSS score (0.44%). Track it; it rarely justifies an emergency change on its own.

Description

There is an information leak vulnerability in the digital media player (DMS) of ZTE's residential gateway product. The attacker could insert the USB disk with the symbolic link into the residential gateway, and access unauthorized directory information through the symbolic link, causing information leak.
