CVE-2016-10401
ZyXEL PK5001Z devices have zyad5001 as the su password, which makes it easier for remote attackers to obtain root access if a non-root account password is known (or a non-root default account exists within an ISP's deployment of these devices).
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 12.3%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
