二、解法步骤 本题附件是一个流量包,流量包的题首先关注http协议,搜下有无flag,然后关注tcp协议。这个题没有http协议的流量,那么看看流量分级: NFS流量占比比较大,它是网络文件系统,网络文件系统是FreeBSD支持的文件系统中的一种,也被称为NFS.NFS。允许一个系统在网络上与它人共享目录和文件。通...
十、流量包隐藏文件之PDF 题目名称:simple_transfer 题目描述: 文件里有flag,找到它 题目writeup: 1.下载附件,用wireshark打开流量文件,搜索flag关键字,并没有发现任何东西 2.将该流量文件上传到kali系统中,用binwalk命令查看该文件包含哪些文件,发现有pdf文件包含其中 binwalk f9809647382a42e5bfb64d7d447b4099_.pc...

6Simple experimenting showed that each character typed into the SSH session is transferred in an SSH-encrypted packet with a length of 36. Also, the last ^D generated an additional packet. So, in sudo_su.pcap, we annotated what was known from the challenge scenario and counted the password...
这里首先要用/api/login/..;/flag绕过鉴权,(login接口不需要登录,后端tomcat处理时会把/..;/当做/../,请求地址就变成了 /flag )。其次在请求头中加入Transfer-Encoding: chunked,使用请求走私,在GET请求中夹带一个POST请求获取到最终flag。最终PoC如下: ...
