Description

Cross-Site Request Forgery (CSRF) Protection Bypass Vulnerability in CodeIgniter4

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');

}

```

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity high, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:L

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.

Weakness class

CVE-2022-24712 is classified as CWE-352: Cross-Site Request Forgery (CSRF). A state-changing request is accepted without proof it was intended, so another site can trigger it using the victim's session.
