 Project: Kafka
  Issue Type: Bug
  Components: KafkaConnect
Reporter: Oleksandr Diachenko
Assignee: Oleksandr Diachenko
 Fix For: 2.7.0


 

When _JsonConverter_ is configured with _schemas.enable=false_ and value, 
exceeding _Double_ is passed, the result is incorrect since the converter trims 
it to _Double:_
{code:java}
Map props = Collections.singletonMap("schemas.enable", false);
converter.configure(props, true);
BigInteger value = BigInteger.valueOf(Long.MAX_VALUE).add(new BigInteger("1"));
String msg = value.toString();
SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());
assertNull(schemaAndValue.schema());
assertEquals(value, schemaAndValue.value());
{code}
 

 Fails with:

 
{code:java}
expected:<9223372036854775808> but was:<-9223372036854775808>
Expected :9223372036854775808

[jira] [Created] (KAFKA-10439) Connect's Values class loses precision for integers, larger than 64 bits

2020-08-26 Thread Oleksandr Diachenko (Jira)

 Summary: Connect's Values class loses precision for integers, 
larger than 64 bits
 Key: KAFKA-10439
 URL: https://issues.apache.org/jira/browse/KAFKA-10439
 Project: Kafka
  Issue Type: Bug
  Components: KafkaConnect
Reporter: Oleksandr Diachenko
Assignee: Oleksandr Diachenko
 Fix For: 2.7.0


The `org.apache.kafka.connect.data.Values#parse` method parses integers, which 
are larger than `Long.MAX_VALUE` as `double` with `

Schema.FLOAT64_SCHEMA`.

 

That means it loses precision for these larger integers.

For example:
{code:java}
SchemaAndValue schemaAndValue = Values.parseString("9223372036854775808");
{code}
returns:
{code:java}
SchemaAndValue{schema=Schema{FLOAT64}, value=9.223372036854776E18}
{code}

 Summary: Connect REST API exposes plaintext secrets in tasks 
endpoint
 Key: KAFKA-8774
 URL: https://issues.apache.org/jira/browse/KAFKA-8774
 Project: Kafka
  Issue Type: Bug
  Components: KafkaConnect
Affects Versions: 2.3.0
Reporter: Oleksandr Diachenko
Assignee: Oleksandr Diachenko


I have configured a Connector to use externalized secrets, and the following 
endpoint returns secrets in the externalized form: 
{code:java}
curl localhost:8083/connectors/foobar|jq
{code}
{code:java}
{
"name": "foobar",
"config": {

"connector.class": "io.confluent.connect.s3.S3SinkConnector",
...
"consumer.override.sasl.jaas.config": 
"org.apache.kafka.common.security.plain.PlainLoginModule required 
username=\"${file:/some/secret/path/secrets.properties:kafka.api.key}\" 
password=\"${file:/some/secret/path/secrets.properties:kafka.api.secret}\";",
"admin.override.sasl.jaas.config": 
"org.apache.kafka.common.security.plain.PlainLoginModule required

...
},
"tasks": [

{ "connector": "foobar", "task": 0 }

],

But another endpoint returns secrets in plain text:

{code}
{code:java}
[

  "connector": "lcc-kgkpm",

 Summary: Connect should have a parameter to disable WADL output 
for OPTIONS method
 Key: KAFKA-7715
 URL: https://issues.apache.org/jira/browse/KAFKA-7715
 Project: Kafka
  Issue Type: Improvement
  Components: config, security
Affects Versions: 2.1.0
Reporter: Oleksandr Diachenko
 Fix For: 2.1.1


Currently, Connect REST API exposes WADL output on OPTIONS method:
{code:bash}
curl -i -X OPTIONS http://localhost:8083/connectors
HTTP/1.1 200 OK
Date: Fri, 07 Dec 2018 22:51:53 GMT
Content-Type: application/vnd.sun.wadl+xml
Allow: HEAD,POST,GET,OPTIONS
Last-Modified: Fri, 07 Dec 2018 14:51:53 PST
Content-Length: 1331
Server: Jetty(9.4.12.v20180830)


http://wadl.dev.java.net/2009/02";>
http://jersey.java.net/"; jersey:generatedBy="Jersey: 2.27 
2018-04-10 07:34:57"/>

http://localhost:8083/application.wadl/xsd0.xsd";>



http://localhost:8083/";>



http://www.w3.org/2001/XMLSchema"; name="forward" style="query" 
type="xs:boolean"/>








http://www.w3.org/2001/XMLSchema"; name="forward" style="query" 
type="xs:boolean"/>








{code}

This can be a potential vulnerability, so it makes sense to have a 
configuration parameter, which disables WADL output.
