Vulnerability from cvelistv5 – Published: 2020-08-26 16:15 – Updated: 2024-11-13 18:13

Title

Cisco Data Center Network Manager Read File Path Traversal Vulnerability

Summary

A vulnerability in a specific REST API of Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, remote attacker to conduct directory traversal attacks on an affected device. The vulnerability is due to insufficient validation of user-supplied input to the API. An attacker with a low-privileged account could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to read arbitrary files on the affected system.

Severity

5.3 (Medium)
