Cisco IOS XR Software Health Check Open Port Vulnerability

A vulnerability in the health check RPM of Cisco IOS XR Software could allow an unauthenticated, remote attacker to access the Redis instance that is running within the NOSi container. This vulnerability exists because the health check RPM opens TCP port 6379 by default upon activation. An attacker could exploit this vulnerability by connecting to the Redis instance on the open port. A successful exploit could allow the attacker to write to the Redis in-memory database, write arbitrary files to the container filesystem, and retrieve information about the Redis database. Given the configuration of the sandboxed container that the Redis instance runs in, a remote attacker would be unable to execute remote code or abuse the integrity of the Cisco IOS XR Software host system.

信息暴露

Cisco IOS XR 信息泄露漏洞

Cisco IOS XR是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XR 存在信息泄露漏洞，该漏洞源于health check RPM 在激活时默认打开TCP端口6379，允许未经身份验证的远程攻击者访问正在NOSi容器内运行的Redis实例，攻击者利用该漏洞可以向Redis容器文件系统写入任意文件，并获取关于Redis数据库的信息。
