📝 LLM Analysis

🔸 Vulnerability Description

• Improper Code Sanitization: The code uses eval with JSON.stringify for sanitization, which is inappropriate for defending against code injection vulnerabilities. Special characters need to be specifically escaped.
  • Web Cookie Secure Disabled By Default: The code sets cookies without the Secure attribute, which makes them vulnerable to man-in-the-middle attacks.

🔸 Recommended Fix

• For Improper Code Sanitization, avoid using eval and use safer alternatives like JSON.parse or other parsing methods that do not execute code.
  • For Web Cookie Secure Disabled By Default, ensure that cookies are set with the Secure attribute to enforce transmission over HTTPS only.

🔸 Additional Notes

• The use of JSON.parse(JSON.stringify(t)) is a placeholder to indicate that eval should be avoided. In practice, ensure that the data being handled is properly sanitized and validated before use.
  • The Secure attribute for cookies is added to ensure they are only transmitted over secure HTTPS connections.

📝 LLM Analysis

🔸 Vulnerability Description

• The code is vulnerable to improper code sanitization, where data flows into eval are incorrectly sanitized using JSON.stringify. This method is inappropriate for defending against this kind of vulnerability because special characters need to be specifically escaped.
  • The code also has a vulnerability related to cookies, where the Secure attribute is not set. This leaves the cookie susceptible to man-in-the-middle attacks.

🔸 Recommended Fix

• For the improper code sanitization, ensure that data passed to eval is properly sanitized by escaping special characters or avoiding the use of eval altogether.
  • For the cookie vulnerability, set the Secure attribute to true to ensure cookies are only sent over HTTPS connections.

🔸 Additional Notes

• The eval function has been replaced with new Function() to execute code safely. This is a safer alternative as it does not have access to the local scope.
  • The Secure attribute for cookies has been added to ensure they are only sent over HTTPS connections.
