>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12306

> Overview:
> In May through June of 2016 a static analysis was performed on version 3.0.5 of the Cassandra
source code. The analysis included an automated analysis using HP Fortify v4.21 SCA and a
manual analysis utilizing SciTools Understand v4. The results of that analysis includes the
issue below.
> Issue:
> In the file NodeTool.java on lines 239, 242 and 291 a string object is used to store
sensitive data. String objects are immutable and should not be used to store sensitive data.
Sensitive data should be stored in char or byte arrays and the contents of those arrays should
be cleared ASAP. Operations performed on string objects will require that the original object
be copied and the operation be applied in the new copy of the string object. This results
in the likelihood that multiple copies of sensitive data will be present in the heap until
garbage collection takes place.
> The snippet below shows the issue on line 239 and 242:
> NodeTool.java, lines 229-243:
> {code:java}
> 229 private String password = EMPTY;
> 230 
> 231 @Option(type = OptionType.GLOBAL, name = {"-pwf", "--password-file"}, description
= "Path to the JMX password file")
> 232 private String passwordFilePath = EMPTY;
> 233 
> 234 @Override
> 235 public void run()
> 236 {
> 237     if (isNotEmpty(username)) {
> 238         if (isNotEmpty(passwordFilePath))
> 239             password = readUserPasswordFromFile(username, passwordFilePath);
> 240 
> 241         if (isEmpty(password))
> 242             password = promptAndReadPassword();
> 243     }
> {code}
