CVE-2018-0296 Uma falha grave em Cisco ASA e Firepower Atualmente Exploradas

Uma nova vulnerabilidade, CVE-2018-0296, rated high-severe is affecting Cisco ASA and Firepower security appliances. The flaw is being exploited in the wild after an exploit of it showed up online a few days ago.

CVE-2018-0296 Official Description

A vulnerability in the web interface of the Cisco Adaptive Security Appliance (TÃO) could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resultando em uma negação de serviço (DoS) condição. It is also possible on certain software releases that the ASA will not reload, but an attacker could view sensitive system information without authentication by using directory traversal techniques.

CVE-2018-0296 is triggered by the lack of proper input validation of the HTTP URL. An attacker could exploit the vulnerability by sending a crafted HTTP request to an affected device. An exploit could allow the attacker to cause a DoS condition or unauthenticated disclosure of information. It should also be noted that this vulnerability applies to IPv4 and IPv6 HTTP traffic.




The CVE-2018-0296 vulnerability affects Cisco ASA software and Cisco Firepower Threat Defense (FTD) Programas, running on the following Cisco products:

3000 Series Industrial Security Appliance (ISA), ASA 1000V Cloud Firewall, TÃO 5500 Series Adaptive Security Appliances, ASA 5500-X Series Next-Generation Firewalls, ASA Services Module for Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers, Adaptive Security Virtual Appliance (ASAv), Firepower 2100 Series Security Appliance, Firepower 4100 Series Security Appliance, Firepower 9300 ASA Security Module, FTD Virtual (FTDv). Cisco Bug IDs: CSCvi16029.

Cisco strongly recommends that customers upgrade to a fixed Cisco ASA software release to remediate this issue,” the company said in the underlying consultivo. Nenhuma solução alternativa está disponível para esta vulnerabilidade. Users that haven’t implemented the patches yet are urged to do so now.

This is not the only vulnerability disclosed in Cisco products – there have been a number of flaws in Cisco switches, next generation firewalls and even security appliances.
