How the Exploit Works
An attacker exploits this vulnerability by creating a specially crafted .DWF3WORK file, which contains malicious code. By getting a user to open this file, the attacker can trigger the vulnerability, allowing the malicious code to execute. The relative path traversal vulnerability exists due to improper input validation within Digilent WaveForms, enabling the attacker to manipulate file paths to access directories or files that should otherwise be inaccessible.
Conceptual Example Code
The following pseudocode demonstrates the conceptual approach an attacker might take to exploit this vulnerability:
# Create a malicious .DWF3WORK file with arbitrary code
malicious_file = create_malicious_file(".DWF3WORK")
# Craft the file path to traverse directories
malicious_path = "../target_directory/" + malicious_file
# Attempt to open the file, triggering the vulnerability
open_file(malicious_path)This code is purely conceptual and is included to demonstrate the potential premise of an attack exploiting this vulnerability.
Mitigation Guidance
Users are advised to apply the vendor-provided patch to remediate this vulnerability. In the absence of such a patch, or pending its application, users can implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation strategy to detect and prevent attempts to exploit this vulnerability.
