> 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.
> getByName() is used in multiple locations within the CASSANDRA source code:
> DatabaseDescriptor.java Line 193, 213, 233, 254, 947, 949
> RingCache.java Line 82
> InetAddressType.java Line 52
> FailureDetector.java Line 186
> Gossiper.java Line 228, 571, 1517, 1522
> CqlBulkRecordWriter.java Line 142, 301
> HintsService.java Line 265
> DynamicEndpointSnitch.java Line 320
> Ec2MultiRegionSnitch.java Line 49
> EndpointSnitchInfo.java Line 46, 51
> PropertyFileSnitch.java Line 175
> ReconnectableSnitchHelper.java Line 52
> SimpleSeedProvider.java Line 55
> MessagingService.java Line 943
> StorageService.java Line 1766, 1835, 2526
> ProgressInfoCompositeData.java Line 96
> SessionInfoCompositeData.java Line 126, 127
> BulkLoader.java Line 399, 422
> SetHostStat.java Line 50
> 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.
> DatabaseDescriptor.java, lines 231-238:
> {code:java}
> 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}
