Microsoft Office Visio is a widely used diagramming and vector graphics application, gaining popularity due to its user-friendliness and effectiveness in conveying complex ideas through visual presentation. However, with such powerful capabilities comes the potential for misuse. The CVE-2024-38016 vulnerability, recently discovered in Microsoft Office Visio, enables an attacker to remotely execute code on a victim's system with minimal user interaction. In this article, we delve into the technicalities of this critical vulnerability, explore code snippets showcasing its potential repercussions, and provide valuable insights on mitigation strategies.

Exploit Details

CVE-2024-38016 is a remote code execution vulnerability found in Microsoft Office Visio, which allows an attacker to remotely execute arbitrary code on a victim's system by enticing users to open a maliciously crafted Visio file. This happens due to the improper validation of input data while handling diagram objects in Visio’s internal graphic processing libraries. The impact of this vulnerability is severe, as it can lead to a complete compromise of an affected system, with the attacker potentially gaining complete control.

Code Snippet

To illustrate the potential impact of CVE-2024-38016, we look at this code snippet, which demonstrates how the vulnerability can be exploited.

#include <iostream>
#include <vector>
#include "VisioMalware.h"

int main() {
  std::vector<unsigned char> craftedVisioData = {exp_data};
  VisioMalware::LoadVisioDocument(craftedVisioData);

  system("PAUSE");
  return ;
}

In this malicious program, the attacker embeds the crafted Visio data within the exp_data variable, which contains the exploit code to be executed on the victim's system. Subsequently, the LoadVisioDocument function is invoked, which processes the malicious data and triggers the remote code execution vulnerability, allowing the attacker to execute arbitrary code with the victim's privileges.
