CVSS: 8.8EPSS: 45%CPEs: 3EXPL: 1CVE-2018-12895 – WordPress Core < 4.9.7 - Authenticated Arbitrary File Deletion
https://notcve.org/view.php?id=CVE-2018-12895
WordPress through 4.9.6 allows Author users to execute arbitrary code by leveraging directory traversal in the wp-admin/post.php thumb parameter, which is passed to the PHP unlink function and can delete the wp-config.php file. This is related to missing filename validation in the wp-includes/post.php wp_delete_attachment function. The attacker must have capabilities for files and posts that are normally available only to the Author, Editor, and Administrator roles. The attack methodology is to delete wp-config.php and then launch a new installation process to increase the attacker's privileges. WordPress hasta la versión 4.9.6 permite que los usuarios Author ejecuten código arbitrario aprovechándose de un salto de directorio en el parámetro thumb en wp-admin/post.php que se pasa a la función unlink en PHP y puede borrar el archivo wp-config.php. • http://packetstormsecurity.com/files/164633/WordPress-4.9.6-Arbitrary-File-Deletion.html http://www.securityfocus.com/bid/104569 https://blog.ripstech.com/2018/wordpress-file-delete-to-code-execution https://lists.debian.org/debian-lts-announce/2018/07/msg00046.html https://wpvulndb.com/vulnerabilities/9100 https://www.debian.org/security/2018/dsa-4250 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
