Jeremiah Jordan updated CASSANDRA-12310:
----------------------------------------
Reproduced In: 3.0.5
> Use of getByName() to retrieve IP address
> -----------------------------------------
>
> Key: CASSANDRA-12310
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12310
> 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:
> There are many places in the Cassandra source code that rely upon a call to
> getByName() to retrieve an IP address. The information returned by
> getByName() is not trustworthy. Attackers can spoof DNS entries and depending
> on getByName alone invites DNS spoofing attacks.
> This is an example from the file DatabaseDescriptor.java where there are
> examples of the use of getByName() on line 193, 213, 233, 254, 947 and 949.
> {code:java}
> DatabaseDescriptor.java, lines 231-238:
> 231 try
> 232 {
> 233 rpcAddress = InetAddress.getByName(config.rpc_address);
> 234 }
> 235 catch (UnknownHostException e)
> 236 {
> 237 throw new ConfigurationException("Unknown host in rpc_address " +
> config.rpc_address, false);
> 238 }
> {code}
