CVE-2025-47129: Out-of-Bounds Write Vulnerability in Adobe Framemaker with Potential for Arbitrary Code Execution

Overview

CVE-2025-47129 is a significant vulnerability discovered in multiple versions of Adobe Framemaker, a renowned desktop publishing software. The vulnerability is classified as an out-of-bounds write flaw and has the potential to enable an attacker to execute arbitrary code within the context of the currently active user. This issue poses a serious risk to organizations and individuals alike, due to its ability to potentially compromise systems or lead to data leakage. Understanding this vulnerability, its potential impact, and the necessary mitigation tactics is vital for all users of the affected software.

How the Exploit Works

The CVE-2025-47129 vulnerability is an out-of-bounds write flaw, which means it occurs when data is written past the end or before the beginning of the intended buffer. In the case of Adobe Framemaker, this vulnerability could be triggered when a user opens a malicious file. This action could overwrite adjacent memory, leading to corruption of relevant data, a crash, or code execution. The arbitrary code would be executed in the context of the user who opened the malicious file, potentially granting the attacker the same privileges as the user.

Conceptual Example Code

While an actual exploit code for this vulnerability is not publicly available, a conceptual example might look something like this:

let buffer = new ArrayBuffer(128);
let dataview = new DataView(buffer);
// The malicious file contains data that causes an out-of-bounds write
for (let i = 0; i < 150; i++) {
dataview.setInt8(i, 'malicious_data');
}
// The code above writes past the end of the buffer

In the above pseudocode, the loop is set to write malicious data past the end of the buffer (128), which could lead to data corruption or arbitrary code execution.

Mitigation Guidance

To mitigate the risks associated with this vulnerability, users are advised to apply the vendor patch as soon as it is available. In the meantime, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. These systems can detect and block attempts to exploit this vulnerability. However, these are not long-term solutions and cannot replace patching the affected software.
