CVE-2026-90847 is an OS command-injection vulnerability in EFM ipTIME C200E firmware 1.094. An unspecified function in the System Setup web-management component inadequately neutralizes attacker-controlled input before it is used in an operating-system command. A remote, authenticated attacker with high privileges can exploit the flaw without user interaction. Public exploit disclosure has been reported.

This two-file repository contains a Python proof-of-concept for an authenticated remote code execution condition in an unidentified embedded camera-management web interface. exploit.py logs in through login_handler.cgi using hard-coded default/private-lab credentials, extracts a JavaScript-delivered session ID, and uploads a multipart restore file to /cgi/iux_set.cgi. Although named malicious.cfg, the uploaded content is a tar archive containing etc/cron.cfg. The restore path is documented as processing this file as crontab content, allowing attacker-controlled commands to run repeatedly. The included operational payload creates a proof file, inserts a firewall rule for TCP/4444, and launches BusyBox telnetd with /bin/sh. README.md describes the affected UI path as Camera Management → System Setup and includes demonstration-video links. No CVE, vendor, model, or firmware version is identified in the repository. Despite the success message stating that the device is rebooting, the script itself does not send a reboot request.
