Introduction

A critical security vulnerability, tracked as CVE-2024-10452, has been recently disclosed and is making headlines across the IT and cybersecurity communities. This flaw, present in several popular enterprise management systems, allows organization admins to delete pending invites that were created in organizations they do not belong to. Such an issue can lead to privilege escalation, data inconsistency, and potential disruption in organizational workflows.

This post will break down the vulnerability with code snippets, discuss exploitation details, highlight the risks, and share links to original references for deeper understanding.

Background

In typical SaaS or enterprise platforms (think GitHub, Azure AD, Slack, etc.), user management lets selected users (often admins) invite new members to an organization. Pending invites are records waiting for the recipient to accept or reject. Admins are supposed to have the power to manage these invites, but only within their own organizations.

Problem Summary

The API endpoint (or backend logic) that handles deletion of pending invites does not properly check whether the acting admin is part of the organization where the invite was created. Instead, it simply checks if the user has “admin” status in any organization. This allows malicious admins to:

Affected Systems

While the issue may appear in multiple products, it was most notably reported against SampleEnterprise Manager v2.8.1 (for educational purposes). Always check with your supplier!

Here's a simplified version of the vulnerable code, where the authorization check is incomplete

@app.route('/pending-invites/delete/<invite_id>', methods=['POST'])
def delete_invite(invite_id):
    user = get_current_user()
    if not user.is_admin:
        abort(403)
    invite = PendingInvite.query.get(invite_id)
    if not invite:
        abort(404)
    db.session.delete(invite)
    db.session.commit()
    return jsonify({'status': 'Invite deleted'})

Correct Code Example

@app.route('/pending-invites/delete/<invite_id>', methods=['POST'])
def delete_invite(invite_id):
    user = get_current_user()
    invite = PendingInvite.query.get(invite_id)
    if not invite:
        abort(404)
    if not user.is_admin_of(invite.organization_id):
        abort(403)
    db.session.delete(invite)
    db.session.commit()
    return jsonify({'status': 'Invite deleted'})

Now, the code checks if the admin belongs to the right organization.

`bash

curl -X POST https://example.com/pending-invites/delete/12345 \

If invite ID 12345 exists in OrgB, and without a proper check, the invite is deleted.

5. OrgB admins/users are never notified; legitimate users cannot complete sign-up.

Monitor API usage for abnormal invite deletions

Developers: Always check permissions scoped to the relevant resource, not just global roles!

Final Thoughts

CVE-2024-10452 is a reminder that even experienced teams can overlook object-level authorization. Always tie authorization not just to roles, but to resources. Stay up to date with CVEs, review your systems, and patch promptly.

Stay safe and secure your org’s invite process!
