CVE-2023-20006

Name of the Vulnerable Software and Affected Versions Cisco Adaptive Security Appliance (ASA) Software (affected versions not specified) Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Appliances (affected versions not specified)

Description A vulnerability in the hardware-based SSL/TLS cryptography functionality could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This issue is due to an implementation error within the cryptographic functions for SSL/TLS traffic processing when they are offloaded to the hardware. An attacker could exploit this vulnerability by sending a crafted stream of SSL/TLS traffic to an affected device, potentially causing an unexpected error in the hardware-based cryptography engine.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
