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 · uneditedSysJust Syuan-Gu-Da-Shih, versions before 20191223, contain vulnerability of Request Forgery, allowing attackers to launch inquiries into network architecture or system files of the server via forged inquests.
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 Request Forgery vulnerability in SysJust Syuan-Gu-Da-Shih (versions before 20191223) that allows attackers to forge requests to probe the server's internal network architecture and access system files. The vulnerability likely stems from insufficient validation of request origins or targets, enabling malicious inquiries to be processed as legitimate.

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.
-
Locate the SysJust Syuan-Gu-Da-Shih installationIdentify the installation directory or service on the system where SysJust Syuan-Gu-Da-Shih is deployed. Look for the main application executable, service, or web application folder.Affected if The software is installed but the version cannot be determined or is confirmed to be present.
-
Determine the installed version numberAccess the application's version information through its web interface, about page, help menu, or check the executable/service properties. If version information is displayed in the UI, note the build or release date.Affected if The version displayed is earlier than build date 20191223 or the version number is less than 20191223.
-
Verify the web management interface is accessibleAttempt to access the application's web interface by navigating to the application's URL or localhost port. Confirm the service is running and responding to HTTP/HTTPS requests.Affected if The web interface is active and accessible without requiring authentication, or authentication can be bypassed.
-
Check for request origin validationInspect the application's configuration files or proxy settings for CSRF protection, origin validation, or referer checking mechanisms. Look for settings related to request validation or origin verification.Affected if No CSRF tokens, origin validation, or referer checking is configured or enabled in the application.
The environment is affected if SysJust Syuan-Gu-Da-Shih is installed with a version or build date earlier than 20191223 and the web interface is accessible and processes requests without proper origin validation.

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 data20191223
Upgrade to version 20191223 or later which contains the security fix. If immediate patching is not possible, implement request validation controls such as CSRF tokens and origin/referer validation to mitigate forged requests.
