Apache2 HTTP TRACE Method Vulnerability

漏洞信息

漏洞名称： Apache2 HTTP TRACE Method Vulnerability

漏洞类型： 配置问题

漏洞等级： 高危

漏洞描述： Apache2是一款广泛使用的开源Web服务器软件，支持多种操作系统，常用于搭建网站和服务。其HTTP TRACE方法默认启用，可能导致安全风险。该漏洞属于配置问题，具体表现为未禁用HTTP TRACE方法，从而可能被利用进行跨站追踪（XST）攻击。攻击者可以通过TRACE方法获取用户的敏感信息，如Cookies和认证令牌，进而进行进一步的攻击。此漏洞的利用不需要认证，且可以远程执行，因此被评级为高危。为了防止此类攻击，建议在Apache配置文件中添加’TraceEnable Off’指令，并重启服务以确保配置生效。
