CVE-2024-51981 is an unauthenticated blind server-side request forgery vulnerability caused by a CRLF injection issue that can be leveraged to perform HTTP request smuggling. The issue occurs in processing associated with the WS-Addressing feature during a WS-Eventing subscription SOAP operation. By injecting crafted CRLF sequences into attacker-controlled input used in the outbound HTTP request construction, an attacker can smuggle and fully control the HTTP data sent by the vulnerable server to a target reachable from that server. The resulting SSRF is blind: the attacker can induce arbitrary outbound HTTP requests but does not receive the response body or other returned data through the vulnerable channel.

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.
