Cisco Nexus Dashboard up to 4.0(1i) REST API Endpoint insertion of sensitive information into sent data

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.

Detailsinfo

A vulnerability was found in Cisco Nexus Dashboard and classified as problematic. This issue affects some unknown processing of the component REST API Endpoint. The manipulation with an unknown input leads to a insertion of sensitive information into sent data vulnerability. Using CWE to declare the problem leads to CWE-201. The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor. Impacted is confidentiality. The summary by CVE is:

A vulnerability in the REST API endpoints of Cisco Nexus Dashboard and Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to view sensitive information or upload and modify files on an affected device. This vulnerability exists because of missing authorization controls on some REST API endpoints. An attacker could exploit th vulnerability by sending crafted API requests to an affected endpoint. A successful exploit could allow the attacker to perform limited Administrator functions, such as accessing sensitive information regarding HTTP Proxy and NTP configurations, uploading images, and damaging image files on an affected device.
