Loading vulnerability…
LibreOffice versions prior to 6.0.7 and 6.1.3 are vulnerable to a directory traversal attack that allows execution of arbitrary macros. An attacker can craft a malicious document that, when opened, causes LibreOffice to execute a Python method from a script located at an arbitrary file system location, relative to the LibreOffice installation directory. This is due to improper sanitization of file paths when loading macros bundled with documents.

This repository contains a single Metasploit module (libreoffice_macro_exec.rb) that exploits CVE-2018-16858, a macro code execution and directory traversal vulnerability in LibreOffice. The exploit works by generating a malicious ODT file that, when opened and interacted with (mouse over event), triggers execution of arbitrary code via a vulnerable Python script (pydoc.py) included with LibreOffice. The module supports both Windows and Linux targets, delivering customizable Meterpreter reverse shell payloads. The main file is written in Ruby and leverages Metasploit's file format, Powershell, and command stager mixins. The exploit is weaponized, allowing attackers to easily generate malicious documents for remote code execution on vulnerable LibreOffice installations.
This repository provides a Python-based generator for malicious FODT (Flat OpenDocument Text) files that exploit CVE-2018-16858, a remote code execution vulnerability in LibreOffice. The structure consists of a Python script (main.py), a template FODT file (FODT-Template), and a README. The main.py script takes user-supplied parameters (target IP/domain, file path, command to execute, and display text) and generates a customized FODT file. The FODT-Template contains an embedded link and an event listener that, when triggered (e.g., by mouseover), executes arbitrary commands on the victim's system via a Python script path (defaulting to pydoc.py). The exploit is operational, allowing attackers to craft documents that, when opened in vulnerable versions of LibreOffice, can execute arbitrary commands. The main attack vector is user-assisted: the victim must open the malicious document and interact with the embedded link. The endpoints of interest are the customizable HTTP link and the file path to the Python script used for code execution.
