-----------------------------------------
Component/s: Auth
> Privacy VIolation - Heap Inspection
> -----------------------------------
>
> Key: CASSANDRA-12306
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12306
> Project: Cassandra
> Issue Type: Sub-task
> Components: Auth
> Reporter: Eduardo Aguinaga
> Priority: Major
>
> 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}
