The CVE-2024-53005 vulnerability found in Substance3D - Modeler software versions 1.14.1 and earlier, brings forth a significant security concern for users. This issue pertains to an out-of-bounds read vulnerability, which, if exploited, could lead to potentially disclosing sensitive memory. This disclosure might enable the attacker to bypass built-in security measures such as Address Space Layout Randomization (ASLR). The exploitation requires user interaction in that the victim must open a malicious file. This long-read post will detail the vulnerability, a code snippet demonstrating the issue, links to original references, and more exploit details.

Vulnerability Details

An out-of-bounds read is a type of vulnerability that occurs when a program reads data from a location outside the designated memory boundary. This can lead to exposure, corruption, or modification of sensitive information that should have remained inaccessible. In the case of Substance3D - Modeler, an attacker can craft a malicious file that exploits the vulnerability, thus exposing sensitive memory. Consequently, the attacker could potentially bypass mitigations like ASLR and put users at further risk.

Consider this code snippet showing a potential exploit of the CVE2024-53005 vulnerability

#include <iostream>
#include <fstream>

using namespace std;

void malicious_out_of_bounds_read(const char *file) {
    ifstream inFile;

    inFile.open(file);
    if (!inFile) {
        cerr << "Unable to open the file";
        exit(1);
    }

    int buffer_size = 128;
    char buffer[128];
    int position = -1;

    inFile >> position;

    // Out-of-bounds read vulnerability
    if (position >=  && position < buffer_size) {
        inFile.read(&buffer[position], buffer_size);
    }

    inFile.close();
}

int main() {
    malicious_out_of_bounds_read("malicious_file.bin");
    return ;
}

In the above code snippet, the function malicious_out_of_bounds_read() reads data from a user-provided binary file. The problem lies in the fact that there is no check for the proper bounds. With a negative value of position, an out-of-bounds read vulnerability occurs, potentially disclosing sensitive memory.

An attacker could exploit this vulnerability by performing the following steps

1. Create a malicious binary file containing data that can trigger the position variable to be a negative number.
2. Send the malicious binary file to the victim or convince the victim to download it from a malicious source.
3. Once the unsuspecting victim opens the file in the Substance3D - Modeler software, the out-of-bounds read vulnerability is triggered.
4. Successful exploitation could lead to sensitive memory disclosure, enabling the attacker to bypass security measures such as ASLR.
