Overview<\/strong><\/p>\n

CVE-2024-40071 is a severe vulnerability found in the Sourcecodester Online ID Generator System 1.0. This vulnerability allows for arbitrary file uploads, leading to the execution of arbitrary code by attackers. Business organizations and individuals who use this system for generating<\/a> IDs are at risk. The severity of this vulnerability is magnified by its potential to lead to system<\/a> compromise or data leakage, which can have severe consequences for the affected entity, including loss of data, financial implications and reputational damage.<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Sourcecodester Online ID Generator System<\/a> | 1.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This vulnerability exploits the file<\/a> upload functionality of the Sourcecodester Online ID Generator System. The system settings file, id_generator\/classes\/SystemSettings.php?f=update_settings, does not adequately validate user-supplied input, allowing an attacker to upload<\/a> and execute a malicious PHP file. This execution can compromise the system and lead to potential<\/a> data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability could be exploited<\/a>. An attacker may craft a malicious PHP file and upload<\/a> it via an HTTP POST request.<\/p>\n

POST \/id_generator\/classes\/SystemSettings.php?f=update_settings HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"uploaded_file\"; filename=\"malicious.php\"\nContent-Type: application\/x-php\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
This request uploads a PHP file containing malicious code, which can then be executed on the server, compromising the system and potentially leading<\/a> to data leakage.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of the affected system<\/a> are advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to provide temporary mitigation. Regularly monitoring system logs<\/a> and network traffic can also help in detecting any unusual activity, and immediate action should be taken if any such activity is detected.<\/p>\n","protected":false},"excerpt":{"rendered":"
