Detailed vulnerability description
The vulnerability allows a local user to bypass authorization and create a temporary address without proper permissions.
The vulnerability exists due to incorrect authorization in the OpenWire protocol component when handling non-durable JMS topic subscription creation on a non-existent address. A local user can exploit improper permission checks during subscription creation to bypass authorization and cause the unintended creation of a temporary address.
Exploitation requires the user to have the 'createDurableQueue' permission but not the 'createAddress' permission, with address auto-creation disabled.
