CVE-2020-3521

Estado: ModificadaMedia (6.5)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
