## Basic Information

[**One Gadget**](https://github.com/david942j/one\_gadget) inaruhusu kupata shell badala ya kutumia **system** na **"/bin/sh". One Gadget** itapata ndani ya maktaba ya libc njia fulani ya kupata shell (`execve("/bin/sh")`) kwa kutumia tu **anwani** moja.\
Hata hivyo, kawaida kuna vizuizi fulani, ambavyo ni vya kawaida na rahisi kuepuka kama `[rsp+0x30] == NULL` Kwa kuwa unadhibiti thamani ndani ya **RSP** unahitaji tu kutuma thamani zaidi za NULL ili kuepuka vizuizi hivyo.

![](<../../.gitbook/assets/image (615).png>)
```python
ONE_GADGET = libc.address + 0x4526a
rop2 = base + p64(ONE_GADGET) + "\x00"*100
```
Ili kupata anwani iliyoonyeshwa na One Gadget unahitaji **kuongeza anwani ya msingi ambapo `libc`** imepakuliwa.

One Gadget ni **msaada mzuri kwa mbinu za Arbitrary Write 2 Exec** na inaweza **kurahisisha mnyororo wa ROP** kwani unahitaji tu kuita anwani moja (na kutimiza mahitaji).
