CVE-2021-1397

MEDIUM 6.1EPSS 0.83%

Does this matter?

Lower severity and a low EPSS score (0.83%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Software could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. This vulnerability is due to improper input validation of the parameters in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website. This vulnerability is known as an open redirect attack, which is used in phishing attacks to get users to visit malicious sites without their knowledge.
