Rewterz Threat Advisory – WordPress Comment Cross-Site Request Forgery Vulnerability

March 19, 2019

Severity

Low

Analysis Summary

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, which allows arbitrary changes to .php files. This is related to wp-admin/includes/ajax-actions.php and wp-includes/comment.php.

Impact

Cross site scripting

Affected Products

WordPress 5.x
The vulnerability is reported in versions prior to 5.1.1.

Remediation

Update to version 5.1.1.
