CVE-2024-51977 is an information disclosure vulnerability affecting a vulnerable device's network-exposed management and printing services. An unauthenticated attacker with access to the device over HTTP (TCP/80), HTTPS (TCP/443), or IPP (TCP/631) can issue a GET request for the URI path /etc/mnt_info.csv without authentication. The device returns a CSV file containing sensitive device information, including the model, firmware version, IP address, and serial number. The flaw is caused by improper restriction of access to sensitive internal resource content exposed through the web or IPP interface.

This repository contains a single Metasploit auxiliary module targeting multiple Brother devices (printers, scanners, label printers) vulnerable to authentication bypass (CVE-2024-51978) and serial number information leak (CVE-2024-51977). The module exploits the fact that the default administrator password can be generated from the device's serial number, which may be obtainable via unauthenticated HTTP, HTTPS, IPP, SNMP, or PJL requests. The module first attempts to retrieve the serial number using the specified protocol, then generates the default password using a pseudo-hashing algorithm, and finally attempts to authenticate to the device's web admin console. If successful, it provides administrator access to the attacker. The module is written in Ruby and is designed to be used within the Metasploit framework. The main attack vector is network-based, targeting exposed management interfaces on the device. The code is operational and provides credential generation and login functionality, but does not deliver a shell or arbitrary code execution.
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.
