How to Fix CVE-2022-24712

To remediate this vulnerability, upgrade all affected Codeigniter4/framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

codeigniter4/framework fixed: 4.1.9
Upgrade codeigniter4/framework to 4.1.9
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for codeigniter4/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24712, inspect your project dependencies for Codeigniter4/framework:

inspect dependencies for codeigniter4/framework

Analyze the terminal output to locate any version of Codeigniter4/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.1.9), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Codeigniter4/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact This vulnerability might allow remote attackers to bypass the CodeIgniter4 CSRF protection mechanism. ### Patches Upgrade to v4.1.9 or later. ### Workarounds These are workarounds for this vulnerability, but **you will still need to code as these after upgrading to v4.1.9**. Otherwise, the CSRF protection may be bypassed. #### When Auto-Routing is Enabled 1. Check the request method in the controller method before processing. E.g.: ```php if (strtolower($this->request->getMethod()) !== 'post') { return $this->response->setStatusCode(405)->setBody('Method Not Allowed'); } ``` #### When Auto-Routing is Disabled Do one of the following: 1. Do not use `$routes->add()`, and [use HTTP verbs in routes](https://codeigniter4.github.io/userguide/incoming/routing.html#using-http-verbs-in-routes). 2. Check the request method in the controller method before processing. E.g.: ```php if (strtolower($this->request->getMethod()) !== 'post') { return $this->response->setStatusCode(405)->setBody('Method Not Allowed'); } ``` ### References - [CodeIgniter4 CSRF protection](https://codeigniter4.github.io/userguide/libraries/security.html#cross-site-request-forgery-csrf) ### For more information If you have any questions or comments about this advisory: * Open an issue in [codeigniter4/CodeIgniter4](https://github.com/codeigniter4/CodeIgniter4/issues) * Email us at [SECURITY.md](https://github.com/codeigniter4/CodeIgniter4/blob/develop/SECURITY.md)
