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
ChestnutCMS v1.5.10 has a SQL injection vulnerability. The content parameter of the cms_content tag can be manipulated in the admin backend and injected into a SQL query when the template is rendered.

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 confidence

ChestnutCMS v1.5.10 contains a SQL injection vulnerability in the cms_content tag's content parameter. Attackers with admin backend access can manipulate this parameter to inject arbitrary SQL queries that execute when templates are rendered.

MitigationReplace dynamic SQL query construction with parameterized queries or prepared statements, and implement strict input validation on the content parameter before using it in database operations.

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 ChestnutCMS installation
    Look for ChestnutCMS files in the web root, typically in directories like /cms/, /chestnut/, or check for chestnut-specific Java/POM files in the application codebase
    Affected if ChestnutCMS is present on the system
  2. Check ChestnutCMS version
    Locate version file or pom.xml in the CMS installation directory and compare the version number to v1.5.10
    Affected if The installed version is v1.5.10 or falls within the v1.5.x range
  3. Verify cms_content tag usage
    Search template files (.ftl, .vm, .jsp) for instances of 'cms_content' tag usage, particularly looking for the 'content' parameter being passed
    Affected if Templates contain cms_content tags with a dynamic content parameter
  4. Identify admin backend access
    Check if admin panels or backend routes for ChestnutCMS are accessible or if user accounts with admin privileges exist in the system
    Affected if Admin backend access is available or configurable
  5. Confirm template rendering flow
    Review the application code to verify that the cms_content tag parameter flows into dynamic SQL query construction without parameterized queries
    Affected if The content parameter from cms_content tag is used in raw SQL queries without prepared statements

You are affected if ChestnutCMS v1.5.10 is installed, the cms_content tag is used in templates, and admin backend access exists enabling manipulation of the content parameter during template rendering.

Mitigation

Replace dynamic SQL query construction with parameterized queries or prepared statements, and implement strict input validation on the content parameter before using it in database operations.
