CVE-2020-3441

Estado: ModificadaMedia (5.3)—

A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to view sensitive information from the meeting room lobby. This vulnerability is due to insufficient protection of sensitive participant information. An attacker could exploit this vulnerability by browsing the Webex roster. A successful exploit could allow the attacker to gather information about other Webex participants, such as email address and IP address, while waiting in the lobby.

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).
