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
An issue in thinkphp v.5.1 allows a remote attacker to execute arbitrary code via the routecheck function

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

ThinkPHP v5.1 contains a remote code execution vulnerability in the routecheck function, allowing unauthenticated remote attackers to execute arbitrary code on the affected server via specially crafted requests.

MitigationUpgrade to a patched version of ThinkPHP (v5.1.42+ or latest v5.1 LTS) or apply official security patches; if immediate patching is not possible, restrict access to vulnerable endpoints at the network level.

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 ThinkPHP installation version
    Check the version.php file in the ThinkPHP core directory, or view the header of any ThinkPHP source file that contains version information. Common paths include /thinkphp/base.php or /thinkphp/convention.php.
    Affected if The installed version matches 5.1.0 or falls within the ThinkPHP v5.1 branch.
  2. Locate the routecheck functionality
    Search the ThinkPHP source code for the routecheck function or RouteCheck class. This is typically found in the routing or request handling module.
    Affected if The routecheck function exists and is accessible in the installed version.
  3. Verify routing accessibility
    Examine the application routing configuration in route/ directory and the URL routing rules defined in the application. Check if route matching is enabled in the application configuration.
    Affected if Route matching is enabled and accessible without authentication.
  4. Check for unauthenticated route access
    Review the application configuration file (config.php or app.php) for route authentication settings. Look for any middleware or filters that may protect the routecheck mechanism.
    Affected if No authentication or authorization is required to access routecheck functionality.
  5. Test route pattern matching behavior
    If safe testing is authorized, send a crafted request that would trigger the routecheck function with a malicious route pattern to observe if the vulnerability is exploitable.
    Affected if The application processes route patterns through routecheck without proper sanitization, allowing arbitrary code execution.

A user is affected if they are running ThinkPHP v5.1 with the routecheck function accessible and without authentication protection on route processing.
