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 · unedited
A flaw has been found in CodePhiliaX Chat2DB up to 0.3.7. This vulnerability affects the function exportTable/exportTableColumnComment/exportView/exportProcedure/exportTriggers/exportTrigger/updateProcedure of the file DMDBManage.java of the component Database Export Handler. This manipulation causes sql injection. It is possible to initiate the attack remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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 confidence

SQL injection vulnerability in CodePhiliaX Chat2DB's Database Export Handler component (DMDBManage.java) affecting multiple export functions (exportTable, exportTableColumnComment, exportView, exportProcedure, exportTriggers, exportTrigger, updateProcedure) up to version 0.3.7. The functions likely accept user-supplied input and concatenate it directly into SQL queries without proper parameterization, allowing remote attackers to inject arbitrary SQL statements.

MitigationUpgrade to a version beyond 0.3.7 if available; otherwise, refactor all affected functions to use parameterized queries/prepared statements instead of string concatenation for SQL construction, and implement strict input validation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Chat2DB installation and version
    Locate the Chat2DB application and determine its version by checking application metadata, pom.xml, or the deployed DMDBManage.java class file. Common locations: application root directory, WEB-INF/lib, or build artifacts.
    Affected if The installed version is 0.3.7 or any earlier version of Chat2DB.
  2. Verify DMDBManage.java component is present
    Search for the file DMDBManage.java or its compiled class in the deployment. This file contains the Database Export Handler with the vulnerable export functions.
    Affected if The DMDBManage.java component exists in the application deployment.
  3. Confirm export functions are exposed
    Check if the following functions are accessible via web API, REST endpoints, or other interfaces: exportTable, exportTableColumnComment, exportView, exportProcedure, exportTriggers, exportTrigger, updateProcedure. Review application routing configuration or API documentation.
    Affected if Any of the export functions (exportTable, exportTableColumnComment, exportView, exportProcedure, exportTriggers, exportTrigger, updateProcedure) are exposed and callable.
  4. Inspect SQL query construction in export handlers
    Review the source code of DMDBManage.java, specifically the listed export functions. Look for direct string concatenation of user-supplied parameters into SQL query strings without using PreparedStatement or parameterized queries.
    Affected if The code uses string concatenation to build SQL queries with user input in any of the affected export functions.

A user is affected if they run Chat2DB version 0.3.7 or earlier AND have the Database Export Handler component with its export functions exposed and accessible.
