Nokia GPON ONT Multiple Vulnerabilities

While investigating an Alcatel Lucent I-240W-Q GPON ONT with firmware 3FE54567BOZJ19, Tenable discovered multiple vulnerabilities. Note that the business unit that maintained the I-240W-Q was purchased by Nokia.

CVE-2019-3917: Remote Enabling of Telnet

Telnet is not enabled by default. However, a remote unauthenticated attacker can enable telnet on the device by sending an HTTP request.

curl http://[router ip]/ote

The attacker can also disable the telnet service.

Indusoft Web Studio and InTouch Edge HMI Remote Code Execution

Tenable discovered an unauthenticated remote command injection vulnerability in Indusoft Web Studio 8.1 SP2. The vulnerability is exercised via the custom remote agent protocol that is typically found on port 1234 or 51234. An attacker can issue a specially crafted command 66 which causes IWS to load a DB connection file off of a network share using SMB. The DB file can contain OS commands that will be executed at the privilege level used by IWS.

[R1] Cisco Adaptive Security Appliance HTTP Privilege Escalation

While examining a Cisco Adaptive Security Appliance, Tenable discovered a privilege escalation vulnerability in the HTTP interface. When command authorization is not enabled, an authenticated remote unprivileged (level 0 or 1) user can change or download files as well as upload or replace software images on the appliance.

A simple proof of concept for downloading the running configuration follows:
