Missing secure obfuscation - JavaScript
Description
It is possible to obtain source code from the application since it has only been partially obfuscated in a secure way. This could allow an attacker to understand the inner workings of the application.
Impact
- Understand the operation of the application in order to increase the attack vector.
- Identify validations performed by the front end.
Recommendation
Perform an obfuscation process to the code exposed in web applications.
Threat
Unauthorized user from the Internet.
Expected Remediation Time
⌚ 60 minutes.

Compliant code
The source code is stored using obfuscation techniques like a rename method
function calculatePay(a b){
while(b.c()){
b.a(true);
c.a();
b(c);
}
}
Non compliant code
The source code has been stored without using any form of obfuscation
function calculatePay(SpecialList clientGroup){
while(clientGroup.HasMore()){
clientGroup.getNext(true);
client.updatePay();
makePay(client);
}
}
