Vulnerability Overview

The dsgvoaio_write_log AJAX action of the DSGVO All in one for WP WordPress plugin before 4.0 did not sanitise or escape some POST parameter submitted before outputting them in the Log page in the administrator dashboard (wp-admin/admin.php?page=dsgvoaiofree-show-log). This could allow unauthenticated attackers to gain unauthorised access by using an XSS payload to create a rogue administrator account, which will be trigged when an administrator will view the logs.

Technical Analysis

REMEDIATION: Update to version 4.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
