How the Exploit Works
The vulnerability stems from an out-of-bounds write issue in the Substance3D – Viewer software. An attacker could craft a malicious file that, when opened by a victim using the vulnerable software, triggers the out-of-bounds write. This could allow the attacker to execute arbitrary code in the context of the current user, potentially compromising the system or leading to data leakage.
Conceptual Example Code
Given the nature of this vulnerability, an example might involve a maliciously crafted 3D file. The exact details would depend on the proprietary file format used by Substance3D – Viewer, but conceptually, it could look something like this:
# Attacker crafts a malicious 3D file
echo "malicious_payload" > crafted_file.3d
# Victim opens the file with the vulnerable software
substance3d-viewer crafted_file.3dIn this simplified example, `malicious_payload` would be replaced with the actual payload that exploits the out-of-bounds write vulnerability. The victim unknowingly triggers the exploit by opening the file with the vulnerable Substance3D – Viewer software.
