CVE-2024-44020 identifies a missing authorization vulnerability in the WP Free SSL – Free SSL Certificate for WordPress and force HTTPS plugin developed by prasadkirpekar, affecting all versions up to and including 1.2.7. The vulnerability arises because the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions related to SSL certificate management and HTTPS enforcement. This missing authorization means that an attacker with limited access to the WordPress backend, or potentially even unauthenticated users depending on the plugin’s exposure, could manipulate SSL settings or force HTTPS configurations without proper administrative approval. Such unauthorized changes could lead to security misconfigurations, redirect users to malicious sites, or disrupt site availability. The vulnerability does not currently have a CVSS score and no public exploits have been reported, but the risk remains significant given the plugin’s role in managing critical security features like SSL and HTTPS enforcement. The issue was reserved in August 2024 and published in November 2024, with no patch links currently available, indicating that users must be vigilant for updates or apply manual mitigations. The plugin is used primarily on WordPress sites, which are globally widespread, increasing the potential attack surface. The missing authorization flaw directly impacts the integrity and availability of the affected systems by allowing unauthorized modifications to security-critical settings.

The missing authorization vulnerability in WP Free SSL plugin can lead to unauthorized users modifying SSL and HTTPS enforcement settings on WordPress sites. This can compromise the integrity of the site by allowing attackers to disable HTTPS, redirect traffic, or introduce insecure configurations, potentially exposing users to man-in-the-middle attacks or data interception. Availability may also be affected if attackers misconfigure SSL settings, causing site outages or loss of secure access. Confidentiality risks arise if attackers redirect traffic to malicious endpoints or intercept sensitive data. The ease of exploitation depends on the attacker’s access level; if no authentication is required, the risk is higher. Given WordPress’s extensive use worldwide, especially among small to medium businesses and bloggers, the scope is broad. The vulnerability could be leveraged to undermine trust in affected sites, damage reputations, and facilitate further attacks such as phishing or malware distribution. Organizations relying on this plugin without proper access controls are at significant risk of unauthorized site manipulation.

1. Immediately restrict access to WordPress admin areas and plugin management interfaces to trusted administrators only. 2. Monitor WordPress logs and plugin configuration changes for unauthorized modifications related to SSL or HTTPS settings. 3. Disable or uninstall the WP Free SSL plugin until a security patch or update is released by the vendor. 4. If patching is not yet available, consider implementing web application firewall (WAF) rules to block unauthorized requests targeting plugin endpoints. 5. Enforce strong authentication mechanisms (e.g., MFA) for all WordPress admin accounts to reduce risk of unauthorized access. 6. Regularly audit installed plugins and remove any that are unnecessary or unmaintained. 7. Educate site administrators about the risks of unauthorized configuration changes and encourage prompt reporting of suspicious activity. 8. Stay informed about vendor updates or security advisories related to this vulnerability and apply patches as soon as they become available.
