Uc-httpd 1.0.0 Default Username Password -

Document ID: UC-HTTPD-2026-01 Version: 1.0 Date: April 18, 2026 Classification: Technical Advisory 1. Executive Summary uc-httpd (Micro HTTP Daemon) version 1.0.0, a lightweight web server commonly deployed in embedded systems, IoT devices, and development environments, contains a hardcoded default username and password ( admin:admin ). This credential pair is enabled by default when the HTTP basic authentication module is activated without explicit user configuration. If unchanged, this exposes administrative interfaces to unauthorized access, allowing potential remote attackers to gain control over the device or application.

echo "myuser:$(openssl passwd -apr1 StrongP@ssw0rd)" > /etc/uc-httpd.passwd Then reference it in uc-httpd.conf : uc-httpd 1.0.0 default username password
