CVE-2023-36846 is a missing authentication for critical function vulnerability in Juniper Networks Junos OS on SRX Series devices affecting the J-Web management interface. A specific request to the J-Web user.php functionality does not require authentication, allowing an unauthenticated network attacker to upload arbitrary files to the device. Juniper describes the direct impact as limited integrity loss affecting part of the file system. Although the standalone impact is constrained, the flaw is significant because it can be combined with other J-Web vulnerabilities, including PHP external variable modification issues, to form a pre-authentication remote code execution chain on affected devices.

This repository contains a working exploit for CVE-2023-36846, a remote code execution vulnerability in Juniper Networks Junos OS (SRX and EX Series) via the J-Web interface. The exploit is implemented in Python (exploit.py) and leverages unauthenticated file upload to place a PHP webshell and a malicious .ini file on the target device. The exploit then uses these files to execute arbitrary commands on the device, providing an interactive shell to the attacker. The main entry point is exploit.py, which supports both single and batch URL targeting, multithreading, and output logging. The exploit interacts with the /webauth_operation.php endpoint on the target and uploads files to /var/tmp/. The repository also includes a requirements.txt for dependencies and a README.md with detailed usage instructions and affected version information. The exploit is operational and provides a real shell on vulnerable devices.
