CVE-2025-58083
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 · uneditedGeneral Industrial Controls Lynx+ Gateway is missing critical authentication in the embedded web server which could allow an attacker to remotely reset the device.
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 confidenceThis is a critical authentication bypass vulnerability in the General Industrial Controls Lynx+ Gateway's embedded web server. The flaw allows unauthenticated remote attackers to reset the device due to missing authentication checks on specific endpoints, potentially causing denial of service and disrupting industrial control operations.

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.
-
Identify Lynx+ Gateway devices on your networkScan your network for devices with product identification strings 'Lynx+' or 'Lynx Plus Gateway' or vendor 'General Industrial Controls'. Use network scanning tools or review asset inventories.Affected if A Lynx+ Gateway device is present in your environment.
-
Locate the embedded web server interfaceCheck if port 80, 443, or common web server ports are open on Lynx+ Gateway devices. Review firewall rules and network configurations to determine web interface accessibility.Affected if The web server interface is network-accessible.
-
Test unauthenticated access to reset endpointsAttempt to access common reset endpoints (such as /reset, /reboot, /factory_reset, or similar paths) via HTTP/HTTPS without providing credentials. Compare behavior against documented authentication requirements.Affected if Reset or reboot actions execute without requiring authentication.
-
Review authentication configurationAccess the web interface with valid credentials and verify that sensitive functions (device reset, configuration changes) require authentication. Check if any endpoints bypass the normal login flow.Affected if Authentication is missing or can be bypassed on device reset endpoints.
Your environment is affected if you have a Lynx+ Gateway with its web interface exposed and specific endpoints allow unauthenticated device reset operations.

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 dataApply the vendor-supplied patch or firmware update immediately to remediate the authentication bypass. If a patch is unavailable, implement network segmentation and firewall rules to restrict access to the web server interface, limiting exposure to trusted networks only.
