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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

CVE-2019-8942

remote code execution in wordpress 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.

CVE-2019-9787

wordpress does not properly filter comment content, leading to Remote Code Execution by unauthenticated users in a default configuration.
This occurs because CSRF protection is mishandled, and because Search Engine Optimization of A elements is performed incorrectly, leading to XSS. The XSS results in administrative access.

For Debian 8 'Jessie', these problems have been fixed in version 4.1.26+dfsg-1+deb8u1.

We recommend that you upgrade your wordpress packages.
