* CVE-2023-0614 ldb: Prevent disclosure of confidential attributesJoseph Sutton2023-03-2012-455/+672
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a hook, acl_redact_msg_for_filter(), in the aclread module, that marks inaccessible any message elements used by an LDAP search filter that the user has no right to access. Make the various ldb_match_*() functions check whether message elements are accessible, and refuse to match any that are not. Remaining message elements, not mentioned in the search filter, are checked in aclread_callback(), and any inaccessible elements are removed at this point. Certain attributes, namely objectClass, distinguishedName, name, and objectGUID, are always present, and hence the presence of said attributes is always allowed to be checked in a search filter. This corresponds with the behaviour of Windows. Further, we unconditionally allow the attributes isDeleted and isRecycled in a check for presence or equality. Windows is not known to make this special exception, but it seems mostly harmless, and should mitigate the performance impact on searches made by the show_deleted module. As a result of all these changes, our behaviour regarding confidential attributes happens to match Windows more closely. For the test in confidential_attr.py, we can now model our attribute handling with DC_MODE_RETURN_ALL, which corresponds to the behaviour exhibited by Windows.

| | | | | | | | | | | | | | | | | | | | | | | | In extended_dn_fix_filter() we had: req->op.search.tree = ldb_parse_tree_copy_shallow(req, req->op.search.tree); which overwrote the parse tree on an existing ldb request with a fixed up tree. This became a problem if a module performed another search with that same request structure, as extended_dn_in would try to fix up the already-modified tree for a second time. The fixed-up tree element now having an extended DN, it would fall foul of the ldb_dn_match_allowed() check in extended_dn_filter_callback(), and be replaced with an ALWAYS_FALSE match rule. In practice this meant that <GUID={}> searches would only work for one search in an ldb request, and fail for subsequent ones. Fix this by creating a new request with the modified tree, and leaving the original request unmodified.
