1. lib/util/HttpHelper.js

🧩 SAST Analysis Summary

Line	Type	Level
139	HttpToHttps	⚠️ WARNING

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http module to make requests, which is an insecure protocol as it transmits data in cleartext. This can lead to data being intercepted by unauthorized actors.

🔸 Recommended Fix

Replace the usage of the http module with the https module to ensure that data is transmitted securely over an encrypted connection.

🔸 Additional Notes

The change ensures that all requests default to using HTTPS, which is more secure than HTTP. This change assumes that the server supports HTTPS. If the server does not support HTTPS, additional configuration may be required to handle such cases.

2. test/Github.js

🧩 SAST Analysis Summary

Line	Type	Level
36	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http module to create a server, which transmits data in cleartext. This can lead to data being intercepted by unauthorized actors.

🔸 Recommended Fix

Use the https module instead of the http module to ensure that data is transmitted securely over TLS/SSL.

🔸 Additional Notes

Ensure that you have a valid SSL certificate and private key file paths specified in the options object. This is necessary for the https server to function correctly.

3. test/QuickTest.js

🧩 SAST Analysis Summary

Line	Type	Level
36	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http module to create an HTTP server, which transmits data in cleartext. This can expose sensitive information to unauthorized actors who might intercept the communication.

🔸 Recommended Fix

Use the https module instead of the http module to ensure that data is encrypted during transmission, providing a secure communication channel.

🔸 Additional Notes

To use the https module, you will need to provide SSL/TLS certificates. This example assumes that the necessary certificates are configured elsewhere in the application.

4. test/V2.js

🧩 SAST Analysis Summary

Line	Type	Level
50	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses http.createServer, which establishes an HTTP server. HTTP is an insecure protocol as it transmits data in cleartext, making it susceptible to interception by unauthorized actors.

🔸 Recommended Fix

Replace http.createServer with https.createServer to ensure that data is transmitted securely using encryption.

🔸 Additional Notes

Ensure that you have an SSL certificate configured and available for use with https.createServer. This change requires additional setup for SSL/TLS certificates to function correctly.

5. test/async/requestor.js

🧩 SAST Analysis Summary

Line	Type	Level
22	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http.createServer method, which sets up a server using the HTTP protocol. HTTP is an insecure protocol because it transmits data in cleartext, making it vulnerable to interception by unauthorized actors.

🔸 Recommended Fix

Replace the http module with the https module to create a server that uses the HTTPS protocol, which encrypts data in transit and provides a secure communication channel.

🔸 Additional Notes

Ensure that you have valid SSL certificates and keys available at the specified paths (path/to/private-key.pem and path/to/certificate.pem). Adjust these paths as necessary for your environment. Additionally, any client making requests to this server will need to use HTTPS and trust the server's certificate.

6. test/async/service.js

🧩 SAST Analysis Summary

Line	Type	Level
18	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http module to create a server, which transmits data in cleartext. This can be intercepted by unauthorized actors, leading to potential data breaches.

🔸 Recommended Fix

Replace the http module with the https module to ensure that data is encrypted during transmission.

🔸 Additional Notes

Ensure that you have valid SSL certificate files (private-key.pem and certificate.pem) and update the file paths accordingly. This change will encrypt data transmitted between the server and clients, enhancing security.

7. test/connect-rest.mocha.js

🧩 SAST Analysis Summary

Line	Type	Level
57	HttpToHttps/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses the http module to create a server, which transmits data in cleartext and is susceptible to interception by unauthorized actors.

🔸 Recommended Fix

Use the https module instead of the http module to ensure that data is encrypted during transmission.

🔸 Additional Notes

Ensure that you have the necessary SSL/TLS certificates configured when switching to the https module. This change is essential to secure data transmission and protect against potential data breaches.

8. test/runServer.js

🧩 SAST Analysis Summary

Line	Type	Level
42	HttpToHttps/test	💡 NOTE
21	WebCookieSecureDisabledByDefault/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code uses http.createServer, which is an insecure protocol for transmitting data as it does not encrypt the data. Additionally, the cookie configuration does not set the Secure attribute, which means cookies could be sent over non-secure connections.

🔸 Recommended Fix

Use the https module instead of http to ensure data is encrypted during transmission. Also, set the Secure attribute to true in the cookie configuration to ensure cookies are only sent over secure connections.

🔸 Additional Notes

Make sure to replace 'path/to/privatekey.pem' and 'path/to/certificate.pem' with the actual paths to your SSL key and certificate files. This change ensures that the server uses HTTPS for secure communication and that cookies are only sent over secure connections.

9. test/restBuilder.js

🧩 SAST Analysis Summary

Line	Type	Level
103	PT/test	💡 NOTE
137	XSS/test	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

• Cross-Site Scripting (XSS): Unsanitized input from an HTTP parameter flows into res.end, where it is used to render an HTML page returned to the user. This may result in a Cross-Site Scripting attack (XSS).
  • Path Traversal: Unsanitized input from an HTTP parameter flows into fs.createReadStream, where it is used as a path. This may result in a Path Traversal vulnerability and allow an attacker to read arbitrary files.

🔸 Recommended Fix

• XSS: Sanitize the input before using it in res.end.
  • Path Traversal: Validate and sanitize the file path to prevent directory traversal attacks.

🔸 Additional Notes

• The Buffer constructor is deprecated, so it is replaced with Buffer.from.
  • The path module is used to sanitize file paths to prevent directory traversal attacks.
  • HTML special characters are escaped to prevent XSS in the getDispatcher function.

10. lib/util/Dispatcher.js

🧩 SAST Analysis Summary

Line	Type	Level
16	reDOS	🛑 ERROR

📝 LLM Analysis

🔸 Vulnerability Description

The code allows unsanitized user input from an HTTP parameter to flow into the matches function, where it is used to build a regular expression. This can lead to a Regular expression Denial of Service (reDOS) attack.

🔸 Recommended Fix

Sanitize the user input before using it in the regular expression to prevent reDOS attacks.

🔸 Additional Notes

The sanitization step replaces any character that is not a letter, number, hyphen, or slash with an empty string. This should mitigate the risk of reDOS by ensuring that the input used in the regular expression is safe. Adjust the sanitization pattern as needed based on the application's requirements.
