CVE-2024-12296 is a critical authorization bypass vulnerability in the Apus Framework plugin for WordPress, identified as CWE-862 (Missing Authorization). The vulnerability exists in the 'import_page_options' function, which lacks proper capability checks before allowing modification of site options. Authenticated users with as low as Subscriber-level privileges can exploit this flaw to update arbitrary options within the WordPress installation. Specifically, attackers can change the default role assigned to new users to 'administrator' and enable user registration, thereby allowing them to create new administrative accounts without legitimate authorization. This results in a severe privilege escalation scenario, compromising the confidentiality, integrity, and availability of the affected WordPress site. The vulnerability affects all versions up to and including 2.3 of the Apus Framework plugin. The CVSS v3.1 base score is 8.8, reflecting the network attack vector, low attack complexity, required privileges at the Subscriber level, no user interaction, and high impact on confidentiality, integrity, and availability. No official patches or updates are currently linked, and no known exploits have been reported in the wild as of the publication date. However, the vulnerability's nature makes it a prime target for attackers aiming to gain full administrative control over vulnerable WordPress sites.

The impact of CVE-2024-12296 is significant for organizations using the Apus Framework plugin on WordPress. Successful exploitation allows attackers to escalate privileges from low-level authenticated users to full administrators, effectively granting complete control over the website. This can lead to unauthorized data access, modification or deletion of content, installation of backdoors or malware, and disruption of site availability. Attackers can also manipulate site configurations, deface websites, or use compromised sites as platforms for further attacks such as phishing or distributing malicious payloads. Given WordPress's widespread use for business, e-commerce, and content management, this vulnerability poses a substantial risk to the confidentiality, integrity, and availability of organizational digital assets. The ability to create new administrator accounts stealthily can result in persistent threats that are difficult to detect and remediate. Additionally, compromised sites may suffer reputational damage and legal consequences if sensitive user data is exposed.

To mitigate CVE-2024-12296, organizations should immediately audit their WordPress installations to identify the presence of the Apus Framework plugin and confirm the version in use. Since no official patch is currently linked, administrators should consider the following specific actions: 1) Temporarily disable or uninstall the Apus Framework plugin until a security update is released. 2) Restrict user roles and permissions rigorously, ensuring that only trusted users have Subscriber-level or higher access. 3) Implement Web Application Firewall (WAF) rules to monitor and block suspicious requests targeting the 'import_page_options' function or attempts to modify site options. 4) Monitor WordPress user registrations and role changes closely for anomalies, including unexpected new administrator accounts. 5) Harden WordPress security by disabling user registration if not required and enforcing strong authentication mechanisms. 6) Regularly back up site data and configurations to enable recovery in case of compromise. 7) Stay informed on vendor updates and apply patches promptly once available. 8) Conduct security audits and penetration testing focused on privilege escalation vectors within WordPress plugins.
