Inteno Routers: JUCI ACL Misconfiguration Allows Unauthorized File Access and SSH Key Manipulation

CVE-2017-11361 · HIGH Severity

AV:N/AC:L/AU:S/C:C/I:C/A:C

Inteno routers have a JUCI ACL misconfiguration that allows the "user" account to read files, write to files, and add root SSH keys via JSON commands to ubus. (Exploitation is sometimes easy because the "user" password might be "user" or might match the Wi-Fi key.)
