Vulnerabilities

Inteno EG200 EG200-WU7P1U_ADAMO3.16.4-190226_1650 routers have a JUCI ACL misconfiguration that allows the "user" account to extract the 3DES key via JSON commands to ubus. The 3DES key is used to decrypt the provisioning file provided by Adamo Telecom on a public URL via cleartext HTTP.

An issue was discovered in the firewall3 component in Inteno IOPSYS 1.0 through 3.16. The attacker must make a JSON-RPC method call to add a firewall rule as an "include" and point the "path" argument to a malicious script or binary. This gets executed as root when the firewall changes are committed.

Inteno DG400 WU7U_ELION3.11.6-170614_1328 devices allow remote attackers to cause a denial of service (connectivity loss) via a series of packets with random MAC addresses, as demonstrated by macof.

read_tmp and write_tmp in Inteno IOPSYS allow attackers to gain privileges after writing to /tmp/etc/smb.conf because /var is a symlink to /tmp.

p910nd on Inteno IOPSYS 2.0 through 4.2.0 allows remote attackers to read, or append data to, arbitrary files via requests on TCP port 9100.

Inteno iopsys 2.0-3.14 and 4.0 devices allow remote authenticated users to execute arbitrary OS commands by modifying the leasetrigger field in the odhcpd configuration to specify an arbitrary program, as demonstrated by a program located on an SMB share. This issue existed because the /etc/uci-defaults directory was not being used to secure the OpenWrt configuration.

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.)
