[jboss-jira] [JBoss JIRA] (WFLY-2317) Trying to remove a server group as a server-group-scoped role leaks information

Trying to remove a server group as a server-group-scoped role leaks information ------------------------------------------------------------------------------- Key: WFLY-2317 URL: https://issues.jboss.org/browse/WFLY-2317 Project: WildFly Issue Type: Sub-task Security Level: Public(Everyone can see) Components: Domain Management Reporter: Ladislav Thon Assignee: Brian Stansberry Labels: rbac-filed-by-qa Fix For: 8.0.0.CR1 When writing a small test case for WFLY-2190, I stumbled upon a problem: trying to remove an existing server group by a server-group-scoped user that does NOT have permissions to that server group leaks information. On a freshly built WildFly with added {{admin}} user into {{domain/configuration/mgmt-users.properties}}, it can be reproduced like this: {code} [1] ./bin/domain.sh [2] ./bin/jboss-cli.sh -c /core-service=management/access=authorization/server-group-scoped-role=NewRole:add(base-role=administrator, server-groups=[main-server-group]) /core-service=management/access=authorization/role-mapping=NewRole:add /core-service=management/access=authorization/role-mapping=NewRole/include=user-admin:add(name=admin, type=user) /core-service=management/access=authorization:write-attribute(name=provider, value=rbac) exit [1] ^C ./bin/domain.sh [2] ./bin/jboss-cli.sh -c --user=admin --password=XXX /server-group=other-server-group:read-resource /server-group=other-server-group:remove {code} What does that mean? The {{NewRole}} is scoped to the {{main-server-group}} server group and can't see {{other-server-group}}. When doing {{/server-group=other-server-group:read-resource}}, this is correctly enforced and the output looks like this: {code} { "outcome" => "failed", "failure-description" => "JBAS014807: Management resource '[(\"server-group\" => \"other-server-group\")]' not found", "rolled-back" => true } {code} However, trying to do {{/server-group=other-server-group:remove}}, which is only a different operation _on the same resource_, I get a different error message: {code} { "outcome" => "failed", "failure-description" => {"domain-failure-description" => "JBAS013456: Unauthorized to execute operation 'remove' for resource '[(\"server-group\" => \"other-server-group\")]' -- \"JBAS013475: Permission denied\""}, "rolled-back" => true } {code} I expect the error message to be completely the same as in previous case, not leaking any information that the {{other-server-group}} actually exists.
