Cisco Security Advisory
Cisco Network Services Orchestrator Network Plug and Play Information
Advisory ID: cisco-sa-20180905-nso-infodis
First Published: 2018 September 5 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvj50567
CVSS Score: Base 5.9
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.
