CVE-2024-6698
📋 TL;DR
The FundEngine WordPress plugin allows authenticated attackers with subscriber-level access or higher to escalate their privileges to administrator. This occurs because the plugin fails to properly validate user meta updates, enabling attackers to modify their own capabilities. All WordPress sites using FundEngine version 1.7.0 or earlier are affected.
💻 Affected Systems
- WordPress FundEngine plugin
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control over the WordPress site, allowing them to install malicious plugins/themes, modify content, steal data, or establish persistent backdoors.
Likely Case
Attackers with existing low-privilege accounts (subscriber, contributor, author) elevate to administrator and perform unauthorized administrative actions.
If Mitigated
With proper access controls and monitoring, privilege escalation attempts are detected and blocked before administrative access is achieved.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once an attacker has any valid user account.
