CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

oaliptaddBridgeIsolationRules on TP-Link TL-WR840N 6EU0.9.14.16 devices allows OS command injection because a raw string entered from the web interface (an IP address field) is used directly for a call to the system library function (for iptables). NOTE: oaliptaddBridgeIsolationRules is not the only function that calls utilexecSystem.
