How the Exploit Works
The exploit works by making use of the use-after-free vulnerability present in Microsoft Office PowerPoint. An attacker can craft a malicious PowerPoint file which, when opened by the victim, executes the attacker’s code within the context of the PowerPoint application. This can potentially lead to compromise of the system or data leakage.
Conceptual Example Code
As the vulnerability is exploited by crafting a malicious PowerPoint file, an HTTP request or shell command example would not be relevant. Conceptually, the attacker would create a PowerPoint file with embedded code that is executed when a certain event is triggered (e.g., opening the file or clicking on a specific element).
Create PowerPoint file
Embed malicious code within file
Set code to execute on event (e.g., file open, element click)
Distribute file to victimsMitigation Guidance
Users are advised to apply the vendor patch as soon as possible. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Users should also be cautious when opening PowerPoint files from unknown or untrusted sources.
