Summary: Privacy VIolation - Heap Inspection
Key: CASSANDRA-12304
URL: https://issues.apache.org/jira/browse/CASSANDRA-12304
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 BulkLoader.java on line 387 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 387:
BulkLoader.java, lines 318-387:
{code:java}
318 public String passwd;
. . .
337 public static LoaderOptions parseArgs(String cmdArgs[])
338 {
339 CommandLineParser parser = new GnuParser();
340 CmdLineOptions options = getCmdLineOptions();
341 try
342 {
. . .
386 if (cmd.hasOption(PASSWD_OPTION))
387 opts.passwd = cmd.getOptionValue(PASSWD_OPTION);
{code}
