CVE-2025-49530: Out-of-Bounds Write Vulnerability in Adobe Illustrator

Overview

In the dynamic landscape of cybersecurity, a new threat has emerged that affects popular versions of Adobe Illustrator – a widely used vector graphics editor. The vulnerability, identified as CVE-2025-49530, is an out-of-bounds write vulnerability that could lead to potential system compromise or data leakage. This vulnerability is significant as Illustrator is extensively used by graphic designers worldwide, and an exploited vulnerability could lead to serious consequences for the user and their data.

Vulnerability Summary

CVE ID: CVE-2025-49530
Severity: High (CVSS: 7.8)
Attack Vector: Local

Impact: Arbitrary code execution leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

Adobe Illustrator | 28.7.6 and earlier
Adobe Illustrator | 29.5.1 and earlier

How the Exploit Works

The vulnerability arises due to inadequate handling of certain types of files by the affected versions of Adobe Illustrator. Specifically, it is an out-of-bounds write vulnerability, meaning that it allows an attacker to write data past the end of allocated objects. This can corrupt data, crash the program, or in worst-case scenarios, lead to arbitrary code execution. Successful exploitation requires a victim to open a maliciously crafted file, which then executes code in the context of the current user.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is represented in pseudocode:

function exploit_CVE-2025-49530(file) {
malicious_payload = generate_malicious_payload()
corrupt_file(file, malicious_payload)
}
function generate_malicious_payload() {
// Returns a payload that exploits out-of-bounds write vulnerability
return crafted_payload
}
function corrupt_file(file, payload) {
// Inserts the payload into the file in such a way that opening the file causes the payload to be executed
file.write(payload)
}

In this example, the `exploit_CVE-2025-49530` function takes a file as input and corrupts it with a malicious payload that exploits the out-of-bounds write vulnerability. The `generate_malicious_payload` function returns this crafted payload, and the `corrupt_file` function writes the payload into the file in a way that results in the payload being executed when the file is opened.
