HTTP: WordPress Comment Content Filter Remote Code Execution
This signature detects attempts to exploit a known vulnerability against WordPress Comment Content Filter. A successful attack can lead to arbitrary code execution.
Extended Description
WordPress before 5.1.1 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, which allows arbitrary changes to .php files. This is related to wp-admin/includes/ajax-actions.php and wp-includes/comment.php.
