CVE-2025-20620
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 · uneditedSQL Injection vulnerability exists in STEALTHONE D220/D340 provided by Y'S corporation. An attacker who can access the affected product may obtain the administrative password of the web management page.
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 confidenceSQL injection vulnerability in the web management interface of STEALTHONE D220/D340 network devices allows attackers who can reach the management page to inject malicious SQL queries and extract the administrative password hash from the underlying database.

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 device modelAccess the device web interface or check physical device label/console output for model number STEALTHONE D220 or D340Affected if Device is STEALTHONE D220 or D340 network device
-
Locate management interface access pointCheck network configuration or firewall rules to determine if the web management interface (typically HTTP/HTTPS on port 80/443 or custom port) is network-accessible from untrusted networksAffected if Web management interface is reachable from network segments outside the trusted administrative network
-
Check firmware versionLog into the device admin panel or use console access to view system information or firmware version - typically found under 'System', 'Status', or 'About' pages in the web UIAffected if Firmware version is unpatched or unknown compared to vendor fixed version (contact STEALTHONE/Y'S corporation for specific fixed version number)
-
Review access logs for SQL injection attemptsIf available, examine device or upstream firewall logs for suspicious SQL patterns in HTTP requests to the management interface - look for keywords like UNION, SELECT, OR 1=1, or quote characters in query parametersAffected if Logs contain SQL injection patterns in requests to the management login or other CGI endpoints
You are affected if you own a STEALTHONE D220 or D340 device with the web management interface exposed to untrusted networks and the firmware is not patched to the vendor-provided fixed version.
Generated from the published advisory. Verify against your own configuration.
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 vendor firmware patch from Y'S corporation when available; until then, restrict network access to the web management interface using firewall rules or network segmentation to prevent unauthorized attackers from reaching it.
