HTTP: WordPress CVE-2019-8942 Remote Code Execution
This signature detects attempts to exploit a known vulnerability against WordPress. A successful attack can lead to arbitrary code execution.
Extended 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.
