Summary: Privacy VIolation - Heap Inspection
Key: CASSANDRA-12305
URL: https://issues.apache.org/jira/browse/CASSANDRA-12305
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 NodeProbe.java on lines 139 and 181 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 139:
NodeProbe.java, lines 105-141:
{code:java}
105 private String password;
. . .
131 public NodeProbe(String host, int port, String username, String password)
throws IOException
132 {
133 assert username != null && !username.isEmpty() && password != null &&
!password.isEmpty()
134 : "neither username nor password can be blank";
135
136 this.host = host;
137 this.port = port;
138 this.username = username;
139 this.password = password;
140 connect();
141 }
{code}
