---------------------------
Assignee: angela
> Remove of Subtree after Move is not subjected to permission validation
> ----------------------------------------------------------------------
>
> Key: OAK-1115
> URL: https://issues.apache.org/jira/browse/OAK-1115
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: core
> Reporter: angela
> Assignee: angela
> Priority: Critical
>
> the following test passes in Jackrabbit-Core but fails in OAK:
> {code}
> @Test
> public void testMoveRemoveSubTree() throws Exception {
> superuser.getNode(childNPath).addNode(nodeName3);
> superuser.save();
> /* allow READ/WRITE privilege for testUser at 'path' */
> givePrivileges(path, privilegesFromNames(new String[]
> {Privilege.JCR_READ, "rep:write"}), Collections.<String, Value>emptyMap());
> /* deny READ/REMOVE property privileges at subtree. */
> withdrawPrivileges(path, privilegesFromNames(new String[]
> {Privilege.JCR_REMOVE_NODE}), Collections.singletonMap("rep:glob",
> superuser.getValueFactory().createValue("*/"+nodeName3)));
> Session testSession = getTestSession();
> assertTrue(testSession.nodeExists(childNPath));
> assertTrue(testSession.hasPermission(childNPath,
> Session.ACTION_REMOVE));
> assertTrue(testSession.hasPermission(childNPath2,
> Session.ACTION_ADD_NODE));
> testSession.move(childNPath, childNPath2 + "/dest");
> Node dest = testSession.getNode(childNPath2 + "/dest");
> dest.getNode(nodeName3).remove();
> try {
> testSession.save();
> fail("Removing child node must be denied.");
> } catch (AccessDeniedException e) {
> // success
> }
> }
> {code}
> this is a critical security issue as it moving around the parent is
> sufficient in order to be able to remove a node that was otherwise not
> removable due to limited permissions.
> Afaik this behavior is caused by a limitation in the Diff process which
> doesn't allow to identify the move and thus makes it impossible to find out
> if that the subtree has been removed.
