Vulnerability mechanics
Root cause
"The plugin uses the eval() function to execute commands sent via POST data without proper sanitization."
Attack vector
An attacker can exploit this vulnerability by sending a crafted POST request to the `wp-admin/admin-ajax.php` endpoint. This request must include the `action` parameter set to `wpCleanFixAjax` and a `command` parameter containing the arbitrary PHP code to be executed. The vulnerability is triggered when the `eval()` function processes the `command` parameter [ref_id=1].
Affected code
The vulnerability resides in the `wpCleanFixAjax` action handler within the `wpCleanFixAjax.php` file. Specifically, lines 30 and 31 are responsible for retrieving the `command` from the POST data and executing it using `eval()` [ref_id=1]. The code is conditionally executed if `is_admin()` and `_wpdk_is_ajax()` return true [ref_id=1].
What the fix does
The patch is not described in the provided text. The advisory indicates that the vulnerability is exploitable via CSRF and that the `eval()` function is used to execute arbitrary PHP code without proper sanitization [ref_id=1]. Remediation would involve removing or sanitizing the use of `eval()` with user-supplied input.
Preconditions
- authThe user must be logged in as an administrator.
- inputThe attacker must be able to send a POST request to the `admin-ajax.php` endpoint.
