Summary: Privacy VIolation - Heap Inspection
Key: CASSANDRA-12298
URL: https://issues.apache.org/jira/browse/CASSANDRA-12298
Project: Cassandra
Issue Type: Bug
Reporter: Eduardo Aguinaga
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 RoleOptions.java on line 89 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 89:
RoleOptions.java, lines 87-90:
87 public Optional<String> getPassword()
88 {
89 return
Optional.fromNullable((String)options.get(IRoleManager.Option.PASSWORD));
90 }
