Vulnerability from cvelistv5 – Published: 2020-10-21 18:41 – Updated: 2024-11-13 17:45

Title

Cisco Firepower Management Center Software Denial of Service Vulnerability

Summary

A vulnerability in the host input API daemon of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted data stream to the host input daemon of the affected device. A successful exploit could allow the attacker to cause the host input daemon to restart. The attacker could use repeated attacks to cause the daemon to continuously reload, creating a DoS condition for the API.
