vulhub/evil-ipp-server

This project is a tool designed to demonstrate a security vulnerability known as CVE-2024-47177. In everyday terms, it sets up a fake printer server that acts maliciously to exploit a flaw in how certain systems handle network printers. The main benefit is for security teams who need to safely test whether their systems can be tricked by a bad actor pretending to be a legitimate printer. At a high level, the tool works by impersonating an IPP (Internet Printing Protocol) server. IPP is a standard language computers and printers use to talk to each other over a network. When a computer or a printing service reaches out to find printers on a network, this fake server responds. Because of the underlying security flaw in the target system, the target trusts this response and can be manipulated, allowing the person running the test to prove the vulnerability exists. The people who would use this are security researchers, IT administrators, and penetration testers. For example, if an IT manager wants to know if their company's computers are vulnerable to this specific printer flaw, they could run this tool on their network. If the fake server successfully interacts with their computers in a malicious way, the IT team knows they need to apply security updates to fix the issue. To use it, someone runs a simple command that tells the script its own address and the address of the computer they want to test. The project is written in Python and is intentionally straightforward. Beyond the basic command to run it, the documentation directs readers to an external web page for the full technical background and details on the vulnerability itself.
