## Injecting Commands

We can add a semi-colon after our input IP `127.0.0.1`, and then append our command (e.g. `whoami`), such that the final payload we will use is (`127.0.0.1; whoami`), and the final command to be executed would be:

```bash
ping -c 1 127.0.0.1; whoami
```

## Other Injection Operators

Such operators can be used for various injection types, like SQL injections, LDAP injections, XSS, SSRF, XML, etc. We have created a list of the most common operators that can be used for injections:

| **Injection Type**                      | **Operators**                                     |
| --------------------------------------- | ------------------------------------------------- |
| SQL Injection                           | `'` `,` `;` `--` `/* */`                          |
| Command Injection                       | `;` `&&`                                          |
| LDAP Injection                          | `*` `(` `)` `&` `\|`                              |
| XPath Injection                         | `'` `or` `and` `not` `substring` `concat` `count` |
| OS Command Injection                    | `;` `&` `\|`                                      |
| Code Injection                          | `'` `;` `--` `/* */` `$()` `${}` `#{}` `%{}` `^`  |
| Directory Traversal/File Path Traversal | `../` `..\\` `%00`                                |
| Object Injection                        | `;` `&` `\|`                                      |
| XQuery Injection                        | `'` `;` `--` `/* */`                              |
| Shellcode Injection                     | `\x` `\u` `%u` `%n`                               |
| Header Injection                        | `\r`  `%0d` `%0a` `%09`                           |

Keep in mind that this table is incomplete, and many other options and operators are possible. It also highly depends on the environment we are working with and testing.
