Title
GO语言httpoxy远程代理感染漏洞
Description
Go语言是谷歌发布的第二款开源编程语言。
httpoxy是一组影响应用程序代码在CGI环境运行的漏洞。该漏洞主要存在于多个Web服务器、Web框架和编程语言中。可对HTTP头部的Proxy字段名变换为“HTTP_PROXY”,Value值不变,进而传递给对应的CGI执行;若CGI或脚本中使用对外请求的组件依赖的是“HTTP_PROXY”环境变量,就可能被污染。未经身份验证的远程攻击者利用漏洞可发起中间人攻击,或在服务器上启动任意主机的连接。
GO语言存在httpoxy远程代理感染漏洞。GO语言net/http包未能解决RFC 3875模式下的命名空间冲突且程序未能正确处理来自HTTP_PROXY环境变量中不可信客户端数据应用程序。远程攻击者利用漏洞通过构造特制的代理将应用程序的出站HTTP流量重定向到任意的代理服务器。
