Simon Scannell of Ripstech Technologies discovered multiple vulnerabilities in wordpress, a web blogging manager.
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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
