    Substance3D – Viewer | 0.25.1 and earlier

    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.3d

    In 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.

This can lead to a variety of impacts, including causing a program to crash, enabling arbitrary code execution, or even allowing for the escalation of privileges.
    The attacker needs to craft a malicious file that, when opened by the victim, exploits the use-after-free condition, thereby allowing the attacker to execute arbitrary code in the context of the current user.

    Conceptual Example Code

    Below is a conceptual example of a payload that could be incorporated into a malicious file to exploit the vulnerability:

    #include <stdlib.h>
// Exploit for CVE-2025-54257
int main() {
char* memory = malloc(100); // Allocate memory
free(memory); // Free the memory
strcpy(memory, "malicious_payload"); // Use the memory after it's been freed
return 0;
}

    This code is a simplified representation and the actual exploit could be more complex, involving specific memory addresses and assembly instructions to gain control over the program execution flow.

    Mitigation Guidance

    Users of the affected products are advised to apply the vendor-supplied patch to mitigate this vulnerability.

The exploitation of this vulnerability requires user interaction, such as opening a malicious file.

    Conceptual Example Code

    The following is a conceptual example demonstrating how the vulnerability might be exploited. The attacker crafts a malicious file that, when opened in the vulnerable version of Premiere Pro, triggers the UAF condition and executes the embedded arbitrary code.

    class MaliciousFile:
def __init__(self):
self.payload = b"\x90" * 200  # NOP sled
self.payload += b"\xcc"  # INT3 - represents malicious code
self.trigger_uaf = False
def open(self):
if self.trigger_uaf:
# Simulate UAF condition
memory = ctypes.string_at(id(self.payload), len(self.payload))
del self.payload
# The memory is now freed, but still used
execute(memory)  # Arbitrary code execution

    This is just a conceptual example, the actual exploit will vary based on the specific conditions of the vulnerable system.
