CVE-2019-8942

Status Candidate

Overview

WordPress before 4.9.9 and 5.x before 5.0.1 allows remote code execution because an _wp_attached_file Post Meta entry can be changed to an arbitrary string, such as one ending with a .jpg?file.php substring. An attacker with author privileges can execute arbitrary code by uploading a crafted image containing PHP code in the Exif metadata. Exploitation can leverage CVE-2019-8943.

WordPress 5.0.0 crop-image Shell Upload
Posted Apr 4, 2019
Authored by RIPSTECH Technology, Wilfried Becard | Site metasploit.com

This Metasploit module exploits a path traversal and a local file inclusion vulnerability on WordPress versions 5.0.0 and versions below or equal to 4.9.8. The crop-image function allows a user, with at least author privileges, to resize an image and perform a path traversal by changing the _wp_attached_file reference during the upload. The second part of the exploit will include this image in the current theme by changing the _wp_page_template attribute when creating a post. This exploit module only works for Unix-based systems currently.
