CVE-2025-58423
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 · uneditedDue to insufficient sanitization, an attacker can upload a specially crafted configuration file to cause a denial-of-service condition, traverse directories, or read/write files, within the context of the local system account.
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 confidenceA file upload vulnerability exists where insufficient input sanitization allows attackers to upload malicious configuration files. This enables directory traversal and arbitrary file read/write operations, potentially executing code in the context of the local system account.

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 if Advantech Deviceon/iedge is installedCheck for the product in common installation directories (e.g., C:\Program Files\Advantech\ or /opt/advantech/) or look for a running service named 'DeviceOn' or 'iedge' in the system service listAffected if The product is found on the system
-
Determine the installed versionLocate version information in the installation directory, typically in an 'about', 'info', or version file, or access the web interface and check the Help/About sectionAffected if The version number is 2.0.2 or lower
-
Identify if the web-based management interface is accessibleCheck if the DeviceOn/iedge web interface is reachable (commonly on ports 8080, 8443, or 443) by accessing the URL in a browser or via curl/PowerShell requestAffected if The web interface is accessible and responds
-
Locate the configuration file upload functionalityNavigate to the settings, system configuration, or file management sections of the web interface to identify where configuration files can be uploadedAffected if A configuration file upload feature exists and is accessible
-
Check current upload restrictionsInspect the application's configuration files (e.g., in the config or settings directory) for file type validation, allowed extensions, or upload size limitsAffected if No file type whitelist or strict validation is configured for uploads
The environment is affected if Advantech Deviceon/iedge version 2.0.2 or lower is installed and the configuration file upload feature is accessible without strict validation controls.

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 dataImplement strict input validation and sanitization for file uploads, enforce allowlists for file types and paths, sanitize configuration file contents, and run upload handlers with least privilege.
