CVE-2020-7374 is a stack-based buffer overflow in Documalis Free PDF Editor 5.7.2.26 and Documalis Free PDF Scanner 5.7.2.122. The vulnerable condition arises because the applications do not appropriately validate the contents of JPEG images embedded within a PDF document. A specially crafted PDF containing malformed or malicious JPEG data can trigger memory corruption on the stack during parsing or processing of the embedded image, which may allow arbitrary code execution in the context of the user running the affected software.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2020-7374) in Documalis Free PDF Editor v5.7.2.26 and Documalis Free PDF Scanner v5.7.2.122 on Windows 7 and Windows 10. The exploit works by generating a malicious PDF file (default name: msf.pdf) containing a specially crafted JPEG image. When the PDF is opened in the vulnerable application, the JPEG image triggers a buffer overflow, allowing execution of arbitrary code as the user. The module allows the attacker to specify any Metasploit payload (up to 1715 bytes), providing remote code execution. The exploit is operational and requires social engineering to convince a user to open the malicious PDF. The repository is structured as a single Ruby file compatible with the Metasploit framework, and does not contain any network endpoints, but targets local file processing in the vulnerable applications.
