A critical security vulnerability, assigned as CVE-2023-26410, has been identified in Adobe Substance 3D Designer version 12.4. and earlier. This vulnerability is categorized as a Use After Free issue, which could potentially allow an attacker to execute arbitrary code in the context of the current user. To exploit this vulnerability successfully, an attacker must convince the target user to open a maliciously crafted file. This post provides an in-depth analysis of this vulnerability, including code snippets, original references, and exploit details.
Adobe Substance 3D Designer is a powerful application used by 3D artists and designers for creating textures, materials, and other essential assets required for 3D modeling and rendering. Its functionalities offer artists the ability to generate complex designs with incredible precision using a procedural and non-destructive workflow.
The CVE-2023-26410 vulnerability is a Use After Free issue arising from improperly managed memory within Adobe Substance 3D Designer. When opening a malicious file, the application fails to ensure the integrity of memory objects after their supposed disposal, resulting in the potential for code execution.
The victim opens the file in Adobe Substance 3D Designer version 12.4. or earlier.
4. The vulnerability is triggered, causing the application to execute arbitrary code in the context of the current user.
Below is a simple yet hypothetical example of how a potential exploit could take place in Adobe Substance 3D Designer:
# Function to initialize a vulnerable object def init_vulnerable_object(): # ... other initialization code ... # Allocate memory for the vulnerable object vulnerable_object = allocate_memory() return vulnerable_object # Function to trigger the Use After Free vulnerability def trigger_vulnerability(vulnerable_object): # ... other code ... # Release memory of the vulnerable object free_memory(vulnerable_object) # ... other code ... # Use the released memory (Use After Free issue) execute_code(vulnerable_object) # Main function def main(): # Create a vulnerable object vulnerable_object = init_vulnerable_object() # Trigger the Use After Free vulnerability trigger_vulnerability(vulnerable_object) if __name__ == "__main__": main()
