As part of ongoing research efforts, a critical security vulnerability has been identified in Adobe Substance 3D Designer version 12.4. and earlier versions. This vulnerability opens up the potential for attackers to execute arbitrary code remotely, putting consumers at risk. Dubbed CVE-2023-26413, this vulnerability is the result of a heap-based buffer overflow bug.

This long read post serves to disseminate accurate and timely information about this newly discovered vulnerability. It provides code snippets, links to original references, and details about the exploit. The resource is written in simple American language to cater to a wide range of audiences.

Heap-based Buffer Overflow

A heap-based buffer overflow occurs when an application writes more data to a buffer than it can hold, causing data to overflow from the buffer onto adjacent memory spaces, potentially overwriting valuable data or causing unexpected behaviors.

The malicious code could be executed in the context of the current user without any warning, essentially hijacking the user's system. The worst-case scenario is arbitrary code execution, enabling remote infiltration, data theft, or sabotage.

Exploitation Details

To exploit this vulnerability, an attacker must craft a malicious file containing specific instruction sets that trigger the heap-based buffer overflow. A victim must then open this file using Adobe Substance 3D Designer version 12.4. or earlier, effectively enabling arbitrary code execution.

The following code snippet illustrates a possible buffer overflow exploit

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void vulnerable_function(char *input) {
    char buffer[256];
    strcpy(buffer, input);
}

int main(int argc, char *argv[]) {
    if (argc != 2) {
        fprintf(stderr, "Usage: %s BUFFER\n", argv[]);
        exit(1);
    }

    // Trigger the heap-based buffer overflow
    vulnerable_function(argv[1]);
}

This example demonstrates buffer overflow vulnerability through a simple call to a vulnerable function that writes user-supplied input to a buffer without checking its size limitations.
