📦 What is this software?

⚠️ Risk & Real-World Impact

🎯 Exploit Status

Hard-coded credentials are trivial to exploit once discovered; public advisories and proof-of-concepts exist.

🔍 How to Verify

Check controller firmware versions against Schneider Electric advisory; attempt authentication with known hard-coded credentials (not recommended in production).

Consult Schneider Electric documentation for specific version checking commands for each controller model.

Verify firmware version matches patched versions in advisory; test that hard-coded credentials no longer work.

📡 Detection & Monitoring

source_ip=* AND (destination_port=502 OR destination_port=80 OR destination_port=443) AND (event_type="authentication" OR event_type="configuration_change")
