CVE-2021-1402 (GCVE-0-2021-1402)

Vulnerability from cvelistv5 – Published: 2021-04-29 17:15 – Updated: 2024-11-08 23:25

Title

Cisco Firepower Threat Defense Software SSL Decryption Policy Denial of Service Vulnerability

Summary

A vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. This crash would then trigger a reload of the device. No manual intervention is needed to recover the device after the reload.

Severity

8.6 (High)
