CVE-2022-22055
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 Le-yan dental management system contains an SQL-injection vulnerability. An unauthenticated remote attacker can inject SQL commands into the input field of the login page to acquire administrator’s privilege and perform arbitrary operations on the system or disrupt service.
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 · high confidenceThe Le-yan dental management system contains a critical SQL injection vulnerability in the login page's input field. An unauthenticated remote attacker can inject malicious SQL commands to bypass authentication, escalate to administrator privileges, and execute arbitrary operations or disrupt service.

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 the installed dental management systemLocate and inspect the software inventory, application metadata, or system documentation to confirm the product name is Le Yan Dental Management SystemAffected if The system is identified as Le Yan Dental Management System and not a different product
-
Verify the exact version numberCheck the application's version information through the admin panel, about page, or system files to confirm the installed version is 2.8.5Affected if The installed version is exactly 2.8.5
-
Confirm the login page is accessibleNavigate to the login page of the web application to verify it is reachable and operationalAffected if The login page is accessible and accepts user input
-
Test login input for SQL injection behaviorIn the login username or password field, submit a test payload such as a single quote (') or SQL-specific syntax and observe if the application returns database error messages or exhibits unexpected behaviorAffected if The application returns SQL error messages, behaves unexpectedly, or allows authentication bypass when special SQL characters are submitted in login fields
-
Check for recent authentication bypass attemptsReview web server logs, application logs, or security monitoring alerts for patterns indicating SQL injection attempts against login endpoints, such as unusual characters in authentication logsAffected if Logs show SQL injection patterns in login requests or evidence of successful unauthorized access
You are affected if you are running Le Yan Dental Management System version 2.8.5 with an accessible login page that exhibits SQL injection vulnerability or shows signs of exploitation attempts.

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 dataReplace dynamic SQL queries in the login functionality with parameterized queries (prepared statements) and implement strict input validation to neutralize SQL injection payloads.
