CVE-2017-20221
Telesquare SKT LTE Router SDT-CS3B1 version 1.2.0 contains a cross-site request forgery vulnerability that allows authenticated attackers to execute arbitrary system commands by exploiting missing request validation.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
