CVE-2021-1589

Estado: ModificadaMedia (6.5)—

A vulnerability in the disaster recovery feature of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain unauthorized access to user credentials. This vulnerability exists because access to API endpoints is not properly restricted. An attacker could exploit this vulnerability by sending a request to an API endpoint. A successful exploit could allow the attacker to gain unauthorized access to administrative credentials that could be used in further attacks.

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).
