CVE-2019-20046
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Synergy Systems & Solutions PLC & RTU system has a vulnerability in HUSKY RTU 6049-E70 firmware versions 5.0 and prior. The affected product does not require adequate authentication, which may allow an attacker to read sensitive information or execute arbitrary code. This is a different issue than CVE-2019-16879 and CVE-2019-20045.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe HUSKY RTU 6049-E70 firmware versions 5.0 and prior contains a critical authentication bypass vulnerability where the affected product does not require adequate authentication. This allows unauthenticated remote attackers to gain unauthorized access to the RTU device, potentially enabling sensitive information disclosure or arbitrary code execution on the industrial control device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device modelIdentify the RTU device on your network or physically inspect the hardware label to verify it is the HUSKY RTU 6049-E70 model. Check the device documentation or management interface for the exact model number.Affected if The device is not a HUSKY RTU 6049-E70 model.
-
Check firmware versionAccess the device management interface, web UI, or use the vendor-provided diagnostic tool to retrieve the installed firmware version. Compare this version against the affected range of <= 5.0.Affected if The installed firmware version is 5.0 or any version lower than 5.0.
-
Verify network accessibilityDetermine if the RTU device management interface (web portal, API, or remote access service) is accessible from network segments outside your trusted internal network, such as the internet or untrusted zones.Affected if The device management interface is exposed to untrusted networks without firewall protection.
-
Test authentication enforcementAttempt to access the device web interface or API endpoints without providing credentials. Observe whether the system grants access or redirects to a login page.Affected if The device allows unauthenticated access to administrative functions or sensitive endpoints.
You are affected if you have a HUSKY RTU 6049-E70 device running firmware version 5.0 or lower, especially if the management interface is accessible from less-trusted network segments.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade HUSKY RTU 6049-E70 firmware to a version newer than 5.0. Until patched, implement network segmentation and restrict external access to the RTU device using firewalls or access controls to minimize attack surface.
