             Summary: Privacy VIolation - Heap Inspection
                 Key: CASSANDRA-12306
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12306
             Project: Cassandra
          Issue Type: Bug
            Reporter: Eduardo Aguinaga
             Fix For: 3.0.5


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}
