Cisco Umbrella Email Enumeration Vulnerability
漏洞描述
中文描述:
Cisco Umbrella是美国思科(Cisco)公司的一套云安全平台。该平台能够预防网络钓鱼、恶意软件和勒索软件等网络威胁。 Cisco Umbrella 存在安全漏洞,该漏洞源于当系统中已经存在新地址时,当用户试图修改其电子邮件地址时,仪表板上出现一个过于描述性的错误消息。攻击者可利用该漏洞枚举系统中用户的电子邮件地址。
英文描述:
A vulnerability in the web-based dashboard of Cisco Umbrella could allow an authenticated, remote attacker to perform an email enumeration attack against the Umbrella infrastructure. This vulnerability is due to an overly descriptive error message on the dashboard that appears when a user attempts to modify their email address when the new address already exists in the system. An attacker could exploit this vulnerability by attempting to modify the user's email address. A successful exploit could allow the attacker to enumerate email addresses of users in the system.
