求教问题 关于海康威视cve-2021-36260的一些问题
看见海康的摄像头存在cve2021-36260的一个漏洞但用网上的cve-36260.py脚本poc的时候 --check 没问题 和-- cmd “ls al”显目录也没问题但在--shell 过程中 提示“stty”不是内部外部命令
查看python源码
os.system(f'stty echo; stty iexten; stty icanon; \
ssh -o StrictHostKeyChecking=no -o LogLevel=error -o UserKnownHostsFile=/dev/null \
P@{args.rhost} -p 1337')
javascript:;
我的pc系统是win10 并非linuxstty命令是打印回显 电脑不能上网内联监控摄像头 （局域网）所以一直能拿到root shell但不知password
虽然本地拿到目录 ls但是无法进入/etc/password得到密码md5值 也无法创建密码
望大佬解惑 刷新最新回复评论栏目的回复 完整脚本发出来 本帖最后由 hagi 于 2023-8-10 08:34 编辑

这段代码里不是说了吗，要通过ssh连进Linux后执行stty命令，所以你Windows不能执行，这不是很正常，又或者说目标并不是运行在Linux之上 90_ 发表于 2023-8-10 17:24

那就没办法了这个poc是国外的wonderfulIP写的没仔细看
我现在的情况 这个主机不能联网 你懂得 而且不能关机不然得话直接在U盘搞个kali
我回去研究研究 看看能不能重写一下
