CVE-2010-20010 is a stack-based buffer overflow in Foxit PDF Reader before 4.2.0.0928. The vulnerability is triggered when the application parses the /Title entry in the PDF Info dictionary without proper bounds checking. A specially crafted PDF containing an overlong Title string can overflow a fixed-size stack buffer and corrupt the Structured Exception Handler (SEH) chain, which can be leveraged to achieve arbitrary code execution when the victim opens the malicious PDF.

This repository contains a single Metasploit module (foxit_title_bof.rb) that exploits a stack buffer overflow vulnerability in Foxit PDF Reader versions prior to 4.2.0.0928 (specifically tested on 4.1.1 for Windows). The exploit works by generating a malicious PDF file with an overly long Title field, which triggers the overflow when opened in the vulnerable application. The module leverages Metasploit's payload system, allowing the attacker to select and encode arbitrary shellcode, which is delivered via the crafted PDF. The exploit does not use JavaScript and instead relies on direct manipulation of the PDF structure and the Title metadata. The only fingerprintable endpoint is the malicious PDF file itself (default name: corelan_foxit.pdf). The code is written in Ruby and is structured as a standard Metasploit exploit module, making use of several Metasploit mixins for file format and PDF manipulation. The exploit is operational and can be used to achieve code execution on vulnerable systems when a user opens the generated PDF file.
