Cisco Network Services Orchestrator Network Plug/Play access control

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Cisco Network Services Orchestrator (affected version not known). It has been rated as critical. Affected by this issue is an unknown code of the component Network Plug/Play. The manipulation with an unknown input leads to a privilege escalation vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was released 10/05/2018 as cisco-sa-20180905-nso-infodis as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is handled as CVE-2018-0463 since 11/26/2017. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

Upgrading eliminates this vulnerability.
