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 CRLF injection vulnerability in Kentico Xperience allows attackers to manipulate URL query string redirects via improper encoding in the routing engine. This could enable header injection and potentially facilitate further web application attacks.

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

CRLF injection vulnerability in Kentico Xperience's routing engine allows attackers to inject carriage return and line feed characters via URL query string parameters used in redirects. Improper encoding of these parameters enables HTTP header injection, potentially splitting responses or setting arbitrary headers to facilitate attacks like session fixation or XSS.

MitigationImplement proper URL encoding for all query string parameters used in redirects. Sanitize or reject input containing CRLF characters ( , ) in redirect parameters. Use built-in framework redirect methods that handle encoding automatically rather than manually constructing redirect URLs.

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 Kentico Xperience installation and version
    Locate the Kentico Xperience instance and determine the installed version number. This is typically found in the application binaries, configuration files, or the CMS administration interface under About/System information.
    Affected if The version is 13.0.79 or lower (any version <= 13.0.79).
  2. Confirm version is within affected range
    Compare your installed version against the affected range: Kentico Xperience versions 13.0.79 and below.
    Affected if Your installed version is 13.0.79 or any lower version number.
  3. Determine if redirect functionality is in use
    Review your application for any redirect operations, particularly those that incorporate URL query string parameters. This includes Response.Redirect, custom redirect handlers, or any code that builds redirect URLs from user-supplied input.
    Affected if Your application performs redirects using query string parameters (this feature must be enabled for the flaw to apply).
  4. Inspect redirect URL construction
    Examine the code responsible for building redirect URLs. Look for any manual string concatenation or URL construction that uses query parameters without proper encoding. Check for direct use of request parameters in redirect targets.
    Affected if Redirect URLs are constructed using query string parameters without proper encoding, or if raw parameter values are appended to redirect URLs.

You are affected if you are running Kentico Xperience version 13.0.79 or lower and your application uses redirect functionality that incorporates query string parameters into redirect URLs.

dbcve · scoped
Upgrade available Upgrade to a release after 13.0.79
Interim mitigation

Implement proper URL encoding for all query string parameters used in redirects. Sanitize or reject input containing CRLF characters ( , ) in redirect parameters. Use built-in framework redirect methods that handle encoding automatically rather than manually constructing redirect URLs.

Recommended fix High confidence

Kentico Xperience 13.0.80 or later

  1. 1. Backup your current Xperience database and application files
  2. 2. Download Kentico Xperience version 13.0.80 or later from the Kentico Customer Portal
  3. 3. Deploy the updated Xperience application files to your environment
  4. 4. Run the database upgrade script if provided with the hotfix
  5. 5. Verify the application functions correctly after the update
  6. 6. Test the URL redirection functionality to confirm the CRLF injection is remediated
Caveat Review Kentico release notes for any breaking changes between your current version and 13.0.80; minor version upgrades typically have minimal breaking changes
