The plan to solve the bug is to integrate CSRF protection into the Express application by adding the csurf
middleware. This will involve updating the package.json
to include the csurf
package, installing the package, and then configuring the middleware in the server.js
file. Additionally, we need to update the authRoutes.js
file to include CSRF tokens in the forms for registration and login and validate these tokens in the POST route handlers.
The bug is caused by the lack of CSRF protection in the application. CSRF attacks exploit the trust that a site has in a user's browser, and without proper CSRF mitigation, attackers can perform unauthorized actions on behalf of authenticated users. The application's current state does not check for CSRF tokens in the request handling process, leaving it vulnerable to such attacks.
To resolve the issue, the following changes should be made:
Update package.json
to include csurf
:
"dependencies": {
// ... other dependencies ...
"csurf": "^1.11.0"
}
Install the csurf
package:
npm install
Import and configure csurf
in server.js
:
const csrf = require('csurf');
const csrfProtection = csrf({ cookie: false });
app.use(csrfProtection);
app.use((req, res, next) => {
res.locals.csrfToken = req.csrfToken();
next();
});
Update authRoutes.js
to include CSRF tokens in forms and validate them:
const csrf = require('csurf');
const csrfProtection = csrf({ cookie: true });
router.get('/auth/register', csrfProtection, (req, res) => {
res.render('register', { csrfToken: req.csrfToken() });
});
router.get('/auth/login', csrfProtection, (req, res) => {
res.render('login', { csrfToken: req.csrfToken() });
});
router.post('/auth/register', csrfProtection, async (req, res) => {
// ... existing code ...
});
router.post('/auth/login', csrfProtection, async (req, res) => {
// ... existing code ...
});
To replicate the bug, perform the following steps:
By following the above solution, the application will be protected against CSRF attacks, and the bug will be resolved.
