ABSTRACT

Obscuring a password with a trivial encoding does not protect the password.

EXPLANATION

Password management issues occur when a password is stored in plaintext in an application's properties or configuration file. A programmer can attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password.


Example: The following code uses a hardcoded password to connect to an application and retrieve addressbook entries:


...
obj = new XMLHttpRequest();
obj.open('GET','/fetchusers.jsp?id='+form.id.value,'true','scott','tiger');
...


This code will run successfully, but anyone who accesses the containing web page will be able to view the password.
