CVE-2015-7283
The web administration interface on ZyXEL NBG-418N devices with firmware 1.00(AADZ.3)C0 has a default password of 1234 for the admin account, which allows remote attackers to obtain administrative privileges by leveraging a LAN session.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
