CORBA34 — Firewall POA Policy does not control access

  • Key: CORBA34-325
  • Legacy Issue Number: 2639
  • Status: open  
  • Source: Anonymous
  • Summary:

    Summary: In orbos/98-07-03 4.9 it says "However, it is desirable to provide a
    portable means by which the object implementor can decide whether an
    object could be accessible through a firewall. The following POA
    policy is defined for this purpose:" but this policy can at most
    control what components are included in references created by the
    POA. Since the references do not have any mechanism to defend against
    forgery, exclusion of a FirewallMechanism component does not prevent
    access through a firewall. If an attacker obtains some other reference
    with the FirewallMechanism component(s), it can convert a reference
    created under NO_EXPORT into the reference that would have been
    created under EXPORT.

    The description of the policy needs to be changed to make it clear
    that the policy does not imply any access control enforcement. The
    ability of an attacker to forge references, either by combining parts
    of other references, or otherwise, should be explicitly stated as a
    security issue that must be addressed by means outside this
    specification.
