RULE（RULE ID：345477）

Rule General Information
Release Date: 2026-08-13
Rule Name: OpenPLC Web Server Default Credentials Login Vulnerability
Severity:
CVE ID:
Rule Protection Details
Description: OpenPLC v3 (open-source IEC 61131-3 PLC runtime, thiagoralves/OpenPLC_v3) ships a web-based HMI/management server initialized with a hard-coded default administrative account (username openplc, password openplc, stored in plaintext). An attacker who can reach the web login (/login, default port 8080) can log in with these well-known default credentials and obtain administrator access to the PLC web interface.
Impact: An attacker could exploit this vulnerability to have unspecified effect.
Affected OS: Windows, Linux, Others

Solutions
Immediately change the default openplc/openplc credentials after first login; do not expose the web server (default TCP 8080) to the internet/untrusted networks; restrict access by IP allow-list; monitor for login attempts using default credentials; upgrade to OpenPLC Runtime v4 where feasible.
