Substance3D – Modeler | versions 1.22.2 and earlier
How the Exploit Works
The vulnerability originates from a use-after-free condition in the Substance3D – Modeler. The software does not correctly handle memory allocation for certain user-supplied input. An attacker who successfully exploits this vulnerability could execute arbitrary code in the context of the current user, leading to unauthorized system access, data manipulation, or even system compromise. Exploitation requires user interaction, specifically the opening of a malicious file.
Conceptual Example Code
While the exact code to exploit this vulnerability would depend on many factors, a conceptual example might look like this:
# pseudo code for the exploit
class MaliciousFile:
def __init__(self, payload):
self.payload = payload
def open_file(self, application):
application.memory_free(self)
application.execute_code(self.payload)
# attacker creates a malicious file
malicious_file = MaliciousFile("arbitrary code")
# victim opens the malicious file using Substance3D Modeler
malicious_file.open_file(Substance3D_Modeler)In this pseudo code, the `MaliciousFile` class represents the malicious file created by the attacker. The `open_file` method mimics the process of opening the file with Substance3D – Modeler. The use-after-free vulnerability is exploited when the application frees up the memory associated with the malicious file and then executes the arbitrary code contained in the payload.
