Overview
CVE-2025-30317 is a significant vulnerability present in InDesign Desktop versions ID20.2, ID19.5.3, and earlier versions. This vulnerability is a form of Heap-based Buffer Overflow that could potentially lead to arbitrary code execution, thereby compromising the users’ systems. This vulnerability becomes a potent threat as it requires just user interaction. The user gets tricked into opening a malicious file, which then exploits the vulnerability, giving the attacker an opportunity to execute arbitrary code under the user’s context.
This vulnerability should not be taken lightly. It exposes millions of users who rely on InDesign Desktop for their daily operations to potential system compromises and data leakage. The severity of the situation calls for immediate attention and remediation to secure the integrity of users’ systems and data.

How the Exploit Works
The exploit leverages a Heap-based Buffer Overflow vulnerability in InDesign Desktop. The attacker crafts a malicious file designed to overflow the buffer in the heap memory of the application. If a user opens this file using an affected version of InDesign Desktop, the malicious code embedded within the file is executed, leading to arbitrary code execution in the user’s context.
Conceptual Example Code
Given the nature of the vulnerability, it is hard to provide an HTTP request or shell command example. However, the pseudocode could look something like this:
open malicious_file.id
if (InDesign_version <= ID20.2) {
overflow_heap_buffer(malicious_code)
execute_arbitrary_code()
}
In this pseudocode, `malicious_file.id` is a file containing the malicious code that triggers the Heap-based Buffer Overflow. When the user opens this file in an affected version of InDesign Desktop, the buffer in the heap memory is overflowed with `malicious_code`, and `execute_arbitrary_code()` function then carries out the arbitrary code execution.
Please note that this is a simplified conceptual representation of the actual exploit. The real-world execution would be far more complex and obscured to avoid detection.
