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。

CVE-2016-5386 (GCVE-0-2016-5386)

Vulnerability from cvelistv5 – Published: 2016-07-19 01:00 – Updated: 2024-08-06 01:00

Summary

The net/http package in Go through 1.6 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
