adfel created SOLR-13472:
----------------------------
Summary: HTTP requests to a node that does not hold a core of the
collection are unauthorized
Key: SOLR-13472
URL: https://issues.apache.org/jira/browse/SOLR-13472
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Authorization
Affects Versions: 8.0, 7.7.1
Reporter: adfel
When creating collection in SolrCloud, collection is available for queries and
updates through all Solr nodes, in particular nodes that does not hold one of
collection's cores. This is expected behaviour that works when using SolrJ
client or HTTP requests.
When enabling authorization rules it seems that this behaviour is broken for
HTTP requests:
- executing request to a node that holds part of the collection (core) obey to
authorization rules as expected.
- other nodes respond with code 403 - unauthorized request.
SolrJ still works as expected.
Tested both with BasicAuthPlugin and KerberosPlugin authentication plugins.
+Steps for reproduce:+
1. Create a cloud made of 2 nodes (node_1, node_2).
2. Configure authentication and authorization by uploading following
security.json file to zookeeper:
{code:java}
{
"authentication": {
"blockUnknown": true,
"class": "solr.BasicAuthPlugin",
"credentials": {
"solr": "'solr' user password_hash",
"indexer_app": "'indexer_app' password_hash",
"read_user": "'read_user' password_hash"
}
},
"authorization": {
"class": "solr.RuleBasedAuthorizationPlugin",
"permissions": [
{
"name": "read",
"role": "*"
},
{
"name": "update",
"role": [
"indexer",
"admin"
]
},
{
"name": "all",
"role": "admin"
}
],
"user-role": {
"solr": "admin",
"indexer_app": "indexer"
}
}
}{code}
3. create 'test' collection with one shard on *node_1*.
--
The following requests expected to succeed but return 403 status (unauthorized
request):
{code:java}
curl -u read_user:read_user "http://node_2/solr/test/select?q=*:*";
curl -u indexer_app:indexer_app "http://node_2/solr/test/select?q=*:*";
curl -u indexer_app:indexer_app "http://node_2/solr/test/update?commit=true";
{code}
Authenticated '_solr_' user requests works as expected. My guess is due to the
special '_all_' role.
