漏洞描述
中文描述:
Duo Network Gateway（DNG）是美国Duo公司的一款用于访问内部Web应用程序的访问控制软件。 Duo Network Gateway存在安全漏洞，攻击者可利用该漏洞获得了DNG日志的访问权限，并且具有拦截和操纵用户与DNG之间的网络流量的能力，可以解密和操纵与DNG及其背后受保护的应用程序的SSL / TLS连接。
英文描述:
Duo has identified and fixed an issue with the Duo Network Gateway (DNG) product in which some customer-provided SSL certificates and private keys were not excluded from logging. This issue resulted in certificate and private key information being written out in plain-text to local files on the DNG host. Any private keys logged in this way could be viewed by those with access to the DNG host operating system without any need for reversing encrypted values or similar techniques. An attacker that gained access to the DNG logs and with the ability to intercept and manipulate network traffic between a user and the DNG, could decrypt and manipulate SSL/TLS connections to the DNG and to the protected applications behind it. Duo Network Gateway (DNG) versions 1.3.3 through 1.5.7 are affected.
