CVE-2021-1143

Estado: ModificadaMedia (4.3)—

A vulnerability in Cisco Connected Mobile Experiences (CMX) API authorizations could allow an authenticated, remote attacker to enumerate what users exist on the system. The vulnerability is due to a lack of authorization checks for certain API GET requests. An attacker could exploit this vulnerability by sending specific API GET requests to an affected device. A successful exploit could allow the attacker to enumerate users of the CMX 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).
