PPPwn is a significant kernel remote code execution (RCE) exploit designed for the PlayStation 4, impacting firmware versions up to 11.00. This exploit is a proof-of-concept demonstration for CVE-2006-4304, which was responsibly disclosed to PlayStation. This article delves into the technical details, requirements, and usage of the PPPwn exploit.
Supported Firmware VersionsThe exploit is compatible with the following PlayStation 4 firmware versions:
- FW 9.00
- FW 11.00
The developers have indicated that support for additional firmware versions could be added, inviting contributions through pull requests (PRs).
Proof-of-Concept FunctionalityInitially, PPPwn only displays "PPPwned" on the PlayStation 4 screen to confirm successful exploitation. For more extensive homebrew applications, such as launching Mira or other enablers, the `stage2.bin` payload must be customized accordingly.
Requirements for Using PPPwnTo utilize the PPPwn exploit, users need the following hardware and software:
- A computer with an Ethernet port (USB Ethernet adapters are also viable)
- An Ethernet cable
- A Linux environment (a Linux VM can be set up using VirtualBox with a Bridged Adapter for network connectivity)
- Python3 and gcc installed on the system
Setting Up and Executing the Exploit##### 1. Preparation:
Users must clone the PPPwn repository from GitHub and install the necessary requirements:
```bash
git clone --recursive https://github.com/TheOfficialFloW/PPPwn
sudo pip install -r requirements.txt
```
##### 2. Compile the payloads:
For firmware 11.00:
```bash
make -C stage1 FW=1100 clean && make -C stage1 FW=1100
make -C stage2 FW=1100 clean && make -C stage2 FW=1100
```
For other firmware versions, adjust the `FW` parameter accordingly (e.g., `FW=900` for firmware 9.00).
##### 3. Run the exploit:
```bash
sudo python3 pppwn.py --interface=enp0s3 --fw=1100
```
For different firmware versions, the `--fw` parameter should be adjusted.
Interaction with PlayStation 4To connect the PlayStation 4 for the exploit:
- Navigate to Settings > Network, and select "Set Up Internet Connection"
- Choose "Use a LAN Cable", opt for "Custom setup", and select "PPPoE" for IP Address Settings
- Enter arbitrary values for the PPPoE User ID and Password
- Select "Automatic" for DNS and MTU Settings, and "Do Not Use" for Proxy Server
- Initiate "Test Internet Connection" to link with the exploit running on the computer
Outcome and TroubleshootingIf executed correctly, the exploit will render a message stating "Cannot connect to network." followed by "PPPwned" on the PlayStation screen. Should there be issues, like a system crash or failed connection, users can retry the connection test after adjusting settings or restarting the exploit script.
PPPwn represents a critical exploration into the security mechanisms of PlayStation 4, illustrating both the potential for system vulnerability exploitation and the importance of responsible vulnerability disclosure and management.
