CVE-2020-11896 is a Ripple20 vulnerability in the Treck TCP/IP stack affecting releases before 6.0.1.66. The IPv4/UDP component improperly handles inconsistent length parameters in an IPv4/UDP packet. An unauthorized network attacker can send a crafted packet that may result in remote code execution. The issue is also described as related to IPv4 tunneling.

This repository contains a proof-of-concept exploit for CVE-2020-11896 (Ripple20), targeting the Digi Connect ME 9210 device running NET+OS 7.5. The main exploit file, 'digi_connect_exploit.py', is a Python script that uses Scapy to craft and send both benign and malformed UDP packets to the target device. The exploit leverages a heap-based buffer overflow in the Track TCP/IP stack to achieve remote code execution. The payload, provided in 'led_shellcode_arm32be', is ARM 32-bit big-endian shellcode, which is injected into the target via the overflow. The script allows the user to specify the target IP address, UDP destination port (default 2362), and other parameters. The exploit is operational and demonstrates the ability to execute arbitrary code on a vulnerable device. The repository also includes a README with background information and a link to a technical whitepaper, as well as a standard MIT license.
