Overview

This report analyzes a critical vulnerability, identified as CVE-2025-9188, found in all versions of Digilent DASYLab. This vulnerability stems from deserialization of untrusted data, potentially resulting in arbitrary code execution. The impact of this vulnerability is significant as it could lead to system compromise or data leakage, thus necessitating immediate attention and mitigation.

How the Exploit Works

The vulnerability is rooted in the deserialization process in DASYLab. An attacker can craft a malicious DSB file containing untrusted data. When a user opens this file in DASYLab, the software deserializes the untrusted data. This activity can lead to an arbitrary code execution within the context of the application. Therefore, an attacker could potentially take control of the system or leak sensitive data.

Conceptual Example Code

A hypothetical example of how an attacker might exploit this vulnerability could look something like this:

# Create a malicious DSB file
echo "malicious_payload" > exploit.dsb
# The victim opens the malicious DSB file in DASYLab
DASYLab.exe exploit.dsb

In this scenario, “malicious_payload” would be replaced with actual malicious code that exploits the deserialization vulnerability, allowing the attacker to execute arbitrary commands or extract sensitive data.

Mitigation Guidance

Users are advised to apply the official vendor patch to mitigate the vulnerability. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as a temporary measure to detect and prevent exploitation of this vulnerability. It is also recommended to avoid opening DSB files from untrusted sources.
