CVE-2024-6210 is an information exposure vulnerability classified under CWE-200 found in the Duplicator – Migration & Backup Plugin for WordPress, developed by smub. This vulnerability affects all versions up to and including 1.5.9. It allows unauthenticated attackers to retrieve the full filesystem path of the WordPress installation. The exposure occurs because the plugin improperly discloses path information in its responses, which can be accessed without any authentication or user interaction. Although the direct impact is limited to information disclosure, the full path can be leveraged by attackers to improve the effectiveness of further attacks, such as local file inclusion, path traversal, or privilege escalation exploits, especially when combined with other vulnerabilities. The vulnerability has a CVSS v3.1 base score of 5.3, indicating a medium severity level. No known exploits have been reported in the wild as of the publication date. The vulnerability was publicly disclosed on July 11, 2024, and no official patches have been linked yet, but users are advised to monitor for updates. The plugin is widely used in WordPress environments for site migration and backup, making this vulnerability relevant to a broad range of websites globally.

The primary impact of CVE-2024-6210 is the exposure of the full filesystem path of WordPress instances to unauthenticated attackers. While this does not directly compromise sensitive data or system integrity, it significantly aids attackers in reconnaissance by revealing directory structures and installation paths. This information can simplify the exploitation of other vulnerabilities, such as local file inclusion or arbitrary file read vulnerabilities, by providing precise path information. For organizations, this can increase the risk of chained attacks leading to data breaches or website defacement. The vulnerability affects all websites using the vulnerable versions of the Duplicator plugin, which is popular among WordPress users for migration and backup tasks. The ease of exploitation (no authentication or user interaction required) increases the likelihood of scanning and reconnaissance activities by attackers. However, since no direct data leakage or system compromise occurs solely from this vulnerability, the immediate risk is moderate. Organizations with high-value web assets or those in regulated industries should consider this a significant risk vector as part of their broader security posture.

1. Monitor the official smub plugin repository and WordPress plugin updates for a patched version of the Duplicator plugin and apply updates promptly once available. 2. Until a patch is released, restrict access to the plugin’s endpoints using web application firewalls (WAFs) or server-level access controls to limit unauthenticated requests. 3. Implement strict file and directory permissions on the web server to minimize the impact of path disclosure. 4. Conduct regular security audits and vulnerability scans to detect any attempts to exploit this or related vulnerabilities. 5. Employ security plugins or tools that can detect and block suspicious reconnaissance activities targeting WordPress plugins. 6. Educate web administrators about the risks of information disclosure and the importance of timely patching. 7. Consider isolating backup and migration tools in separate environments or restricting their usage to trusted IP addresses to reduce exposure. 8. Review server and application logs for unusual access patterns that may indicate exploitation attempts.
