RUB-NDS/PRET
PRET
PRET is a network printer exploitation framework and security utility designed for discovering printing hardware and auditing firmware. It serves as a toolkit for penetrating printing infrastructure by manipulating printer-specific control languages and protocols.
The project provides specialized capabilities for triggering remote code execution via buffer overflows and managing printer file systems using the Printer Job Language. It allows for the extraction of device metadata, such as firmware versions and memory resources, and the modification of hardware behaviors and system parameters.
The framework covers a broad security testing surface, including network device discovery, vulnerability assessment through input flooding, and the interception of print workflows. It also includes tools for system information extraction and hardware-level denial-of-service testing.
Features
- Firmware Exploitation - Delivers crafted payloads via printer languages to trigger buffer overflows and gain unauthorized remote code execution.
- Network Hardware Penetration Tools - Serves as a security utility for discovering printing hardware and intercepting print jobs on local networks.
- Printer-Specific File Access - Reads and writes files on internal device storage using specific control languages to identify sensitive data.
- Remote Device File System Analysis - Allows accessing and modifying internal storage on remote printers to extract sensitive credentials and configuration files.
- Printer File Managers - Provides capabilities to navigate, delete, and modify files and directories on a remote printer's storage.
- PJL File Management - Implements a manager for reading, writing, and modifying files on printer internal storage using the Printer Job Language.
- Firmware Vulnerability Assessment - Extracts device metadata and tests firmware vulnerabilities like buffer overflows through crafted payloads.
