CVE-2020-3361

Estado: ModificadaCrítica (9.8)—

A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to gain unauthorized access to a vulnerable Webex site. The vulnerability is due to improper handling of authentication tokens by a vulnerable Webex site. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Cisco Webex Meetings Server site. If successful, the attacker could gain the privileges of another user within the affected Webex site.

CVSS

Probabilidad de explotación (EPSS)
