Improper Control of Generation of Code ('Code Injection')
CVE CVE-2019-8942
CVSS 8.8 (High)
Publicly Published February 19, 2019
Last Updated January 22, 2024
Researcher Simon Scannell

Description

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.
