CVE-2024-51982 is a denial-of-service vulnerability in devices exposing a raw printing service on TCP port 9100 and accepting Printer Job Language (PJL) commands. An unauthenticated remote attacker can send a PJL command that sets the FORMLINES variable to a non-numeric malformed value. Improper handling of this invalid input causes the target device to crash and reboot. Because the same malformed PJL command can be resent after the device comes back online, the condition can be triggered repeatedly, resulting in a persistent service disruption. Based on the available description, the issue is consistent with improper input validation of a PJL variable value.

This repository contains proof-of-concept (PoC) exploit scripts for seven vulnerabilities (CVE-2024-51977 through CVE-2024-51983) affecting Brother multifunction printers and related OEM devices. Each exploit is implemented as a standalone Ruby script, targeting a specific CVE. The exploits cover a range of attack types: - CVE-2024-51977: Leaks sensitive information from the printer via unauthenticated HTTP(S)/IPP request to /etc/mnt_info.csv. - CVE-2024-51978: Allows an unauthenticated attacker to generate the device's default administrator password, either by leaking the serial number or by providing it directly. - CVE-2024-51979: Authenticated stack-based buffer overflow via crafted HTTP requests, potentially leading to code execution or denial of service. - CVE-2024-51980: Unauthenticated SSRF/port scan via SOAP requests, allowing the attacker to force the printer to open TCP connections to arbitrary internal hosts/ports. - CVE-2024-51981: Unauthenticated SSRF, forcing the device to perform arbitrary HTTP requests to internal or external hosts. - CVE-2024-51982: Unauthenticated device crash via malformed PJL commands sent over TCP port 9100. - CVE-2024-51983: Unauthenticated device crash via crafted SOAP requests to the printer's web services endpoint. The repository also includes a ReadMe.md with detailed descriptions, affected models, and usage instructions, as well as a simple Sinatra server (sinatra_server.rb) for testing SSRF payloads. All scripts are written in Ruby and require minimal dependencies (primarily 'httparty'). The exploits are PoC-level and focus on demonstrating the vulnerabilities rather than providing weaponized payloads. The main attack vector is network-based, targeting exposed printer services over HTTP, HTTPS, IPP, and PJL.
