What is CVE-2020-3124? In plain terms.
It can be attacked from anywhere on the internet without logging in, but a person has to take an action first. If it works, the attacker can change data.
A vulnerability in the web-based interface of Cisco Hosted Collaboration Mediation Fulfillment (HCM-F) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections by the affected software. An attacker could exploit this vulnerability by persuading a targeted user to click a malicious link. A successful exploit could allow the attacker to send arbitrary requests that could change the password of a targeted user. An attacker could then take unauthorized actions on behalf of the targeted user.
