CVE-2018-19239
TRENDnet TEW-673GRU v1.00b40 devices have an OS command injection vulnerability in the start_arpping function of the timer binary, which allows remote attackers to execute arbitrary commands via three parameters (dhcpd_start, dhcpd_end, and lan_ipaddr)…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
