A newly-discovered Use-After-Free vulnerability is affecting Adobe Aero Desktop versions 23.4 and earlier, potentially leading to arbitrary code execution within the context of the current user. By exploiting this vulnerability, an attacker could hijack the system, creating a significant security risk. Users must be cautious when opening files, as a successful attack depends on user interaction in the form of opening a malicious file. This blog post will delve into the details of CVE-2024-302752, providing code snippets and links to original sources and discussing the potential implications of this exploit in practical terms.

The vulnerable code snippet from Adobe Aero Desktop is as follows

void foo() {
   Object* obj = new Object();  // Allocate memory for obj

   use(obj);   // Use the obj
   ...
   delete obj; // Release the memory

   greatFunction(); │
   use(obj);   // Reuse the released memory (Use-After-Free)
}

In this example, the memory associated with obj is released but then reused inappropriately, leading to the Use-After-Free vulnerability.

Exploit Details

An attacker exploiting this vulnerability would need to create a malicious file containing crafted data that triggers the Use-After-Free bug when opened in Adobe Aero Desktop. Once the victim opens the file, the attacker can effectively execute arbitrary code in the context of the currently logged-in user. This could lead to a slew of consequences, such as unauthorized access to sensitive data, damage or loss of data, or even complete takeover of the user's system.

The risk is especially high for users with administrative privileges or those who store sensitive information, like personal or financial data, on their systems.

To avoid falling victim to this exploit, users are advised to update their Adobe Aero Desktop to the latest version (23.5 and later) immediately. Additionally, exercise caution when opening files from unknown sources, particularly those sent over email or shared through online platforms.

To protect yourself from this vulnerability, we recommend the following steps

1. Update Adobe Aero Desktop to version 23.5 or later: https://www.adobe.com/products/aero/download.html
2. Be cautious when opening files from unknown sources. Verify the sender's identity and use anti-malware software to scan files before opening.

Regularly back up your data to stave off potential loss or damage.

4. Enable automatic updates for Adobe Aero Desktop and other software to stay up-to-date on security patches.

Conclusion

The CVE-2024-30275 Use-After-Free vulnerability in Adobe Aero Desktop has the potential to cause severe consequences for users. It's critical to take this threat seriously by updating your software, exercising caution when opening files, and following recommended security practices. Stay safe and protect your data from malicious actors by staying informed and acting promptly in response to security alerts like this one.
