Description

Codeigniter4's Secure or HttpOnly flag set in Config\Cookie is not reflected in Cookies issued

Impact

Setting $secure or $httponly value to true in Config\Cookie is not reflected in set_cookie() or Response::setCookie().

> Note

> This vulnerability does not affect session cookies.

The following code does not issue a cookie with the secure flag even if you set $secure = true in Config\Cookie.

```php

helper('cookie');

$cookie = [

'name' => $name,

'value' => $value,

];

set_cookie($cookie);

// or

$this->response->setCookie($cookie);

```

Patches

Upgrade to v4.2.7 or later.

Workarounds

1. Specify the options explicitly.

```php

helper('cookie');

$cookie = [

'name' => $name,

'value' => $value,

'secure' => true,

'httponly' => true,

];

set_cookie($cookie);

// or

$this->response->setCookie($cookie);

```

2. Use Cookie object.

```php

use CodeIgniter\Cookie\Cookie;

helper('cookie');

$cookie = new Cookie($name, $value);

set_cookie($cookie);

// or

$this->response->setCookie($cookie);

```

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, 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 low, integrity none, availability none.

CVSS metrics in full

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

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • 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: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
