CVE-2019-11535
Unsanitized user input in the web interface for Linksys WiFi extender products (RE6400 and RE6300 through 1.2.04.022) allows for remote command execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
