Vulnerability from fkie_nvd - Published: 2020-08-26 17:15 - Updated: 2026-06-17 03:18
Severity
8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
Summary
A vulnerability in a specific REST API method of Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, remote attacker to conduct a path traversal attack on an affected device. The vulnerability is due to insufficient validation of user-supplied input to the API. An attacker could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device.
