CWE-264

Summary

  o 
    A vulnerability in the Cisco Network Plug and Play server component of
    Cisco Network Services Orchestrator (NSO) could allow an unauthenticated,
    remote attacker to gain unauthorized access to configuration data that is
    stored on an affected NSO system.

    The vulnerability exists because the Network Plug and Play component
    performs incomplete validation when configured to use secure unique device
    identifiers (SUDI) for authentication. An attacker who controls a Cisco
    device that supports SUDI authentication and has connectivity to an
    affected NSO system could exploit this vulnerability. The attacker would
    need to leverage information about the devices that are being registered on
    the NSO server to send crafted Cisco Network Plug and Play authentication
    packets to an affected system. A successful exploit could allow the
    attacker to gain unauthorized access to configuration data for devices that
    will be managed by the NSO system.

    There are no workarounds that address this vulnerability.
