Overview
CVE-2025-30310 is a significant security vulnerability that affects Dreamweaver Desktop versions 21.4 and earlier. The vulnerability is based on an Access of Resource Using Incompatible Type, also known as a ‘Type Confusion’ vulnerability. This vulnerability can result in arbitrary code execution in the context of the current user. The implications of this vulnerability are severe because if successfully exploited, it could potentially lead to system compromise or data leakage. Therefore, users of Dreamweaver Desktop versions 21.4 and earlier should be aware of this vulnerability and take immediate action to mitigate its potential impact.

How the Exploit Works
The CVE-2025-30310 vulnerability arises from an Access of Resource Using Incompatible Type (‘Type Confusion’) issue in Dreamweaver Desktop versions 21.4 and earlier. This occurs when the software incorrectly handles memory objects, leading to a type confusion condition. If an attacker can trick a victim into opening a malicious file, the attacker can exploit this vulnerability to execute arbitrary code in the context of the current user. This could potentially lead to system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This pseudocode shows how an attacker might construct a malicious file to trigger the ‘Type Confusion‘ condition:
var maliciousFile = new File("maliciousFile.drw");
maliciousFile.write("type_confusion_trigger_code");In this example, `maliciousFile.drw` is prepared with specific code designed to trigger the ‘Type Confusion’ vulnerability when opened in Dreamweaver Desktop version 21.4 or earlier. When the victim opens the file in the vulnerable software, the malicious code is executed, leading to arbitrary code execution.
