❗Cycode: SAST violation: 'Missing server configuration to reduce server fingerprinting'.

Severity: Medium

Description

Reducing server fingerprinting enhances security by making it harder for attackers to identify the software your server is running. Server fingerprinting involves analyzing the unique responses of server software to specific requests, which can reveal information about the server's software and version. While not a direct security vulnerability, minimizing this information leakage is a proactive step to obscure details that could be used in targeted attacks.

Cycode Remediation Guideline

✅ Do

Do disable the X-Powered-By header in Express.js applications to prevent revealing the server's technology stack. Use the app.disable() method to achieve this.

app.disable('x-powered-by');

+app.post('/api/data', authenticateJWT, (req, res) => {
+  const { inputData } = req.body;
+  // XSS vulnerability: No sanitization of user input
+  const responseData = `<div>User Input: ${inputData}</div>`;


❗Cycode: SAST violation: 'Unsanitized user input in raw HTML strings (XSS)'.

Severity: High

Description

Including unsanitized user input in HTML exposes your application to cross-site scripting (XSS) attacks. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users.

Cycode Remediation Guideline

✅ Do

Do use a framework or templating language that automatically handles the encoding and sanitization of user input when constructing HTML. This approach minimizes the risk of XSS attacks.

Do sanitize user input if you must use HTML strings directly. Utilize libraries designed for input sanitization to ensure that user input does not contain malicious content.

import sanitizeHtml from 'sanitize-html' const sanitizedTitle = sanitizeHtml(req.params.title) const html = `<h1>${sanitizedTitle}</h1>`

❌ Don't

Do not include user input directly in HTML strings. This practice can lead to XSS vulnerabilities.

const html = `<h1>${req.params.title}</h1>` // unsafe

❗Cycode: SAST violation: 'Missing Helmet configuration on HTTP headers'.

Severity: Medium

Description

Helmet can help protect your app from some well-known web vulnerabilities by setting HTTP headers appropriately. Failing to configure Helmet for HTTP headers leaves your application vulnerable to several web attacks.

Cycode Remediation Guideline

✅ Do

Do use Helmet middleware to secure your app by adding it to your application's middleware.

const helmet = require("helmet"); app.use(helmet());

❗Cycode: SAST violation: 'Leakage of sensitive information in logger message'.

Severity: Medium

Description

Sensitive information leakage through logger messages can compromise user privacy and security. This vulnerability occurs when sensitive data, such as personal identifiable information (PII), is included in log messages, making it accessible to unauthorized individuals.

Cycode Remediation Guideline

✅ Do

Do use non-sensitive, unique identifiers to reference users in log messages. This approach maintains user privacy while still allowing for effective logging.

logger.info(`User is: ${user.uuid}`)

❌ Don't

Do not include sensitive data in logger messages. This can lead to unintended exposure of private information.

logger.info(`User is: ${user.email}`) // unsafe

❗Cycode: SAST violation: 'Leakage of sensitive data in JWT'.

Severity: High

Description

Storing sensitive data in JWTs exposes it to potential security risks. JWTs are designed for transmitting data securely among parties but are not inherently secure storage for sensitive information.

Cycode Remediation Guideline

✅ Do

Do use non-sensitive, unique identifiers like a user's UUID in JWTs to reference user information securely.

const jwt = require('jsonwebtoken'); const token = jwt.sign({ user: user.uuid });

❌ Don't

Do not include sensitive data, such as email addresses, in JWTs. This can lead to unauthorized access to personal information.

const jwt = require('jsonwebtoken'); const token = jwt.sign({ user: { email: 'john@gmail.com' }}); // unsafe
