CVE-2026-8705

Estado: AplazadaAlta (7.5)—

The ClearSale Total plugin for WordPress is vulnerable to SQL Injection via the `pagseguro[metodo]` POST parameter of the `clearsale_total_push` AJAX action in all versions up to, and including, 3.4.2. The handler is registered for unauthenticated users (`wp_ajax_nopriv_clearsale_total_push`), and although a `wp_verify_nonce()` check exists, the failing branch's `die()` is commented out so execution continues regardless of nonce validity.

Leer descripción completaMostrar menos

On PHP < 8.0 the attacker-supplied `$metodo` value bypasses the `switch ($metodo) { case 4: ... }` guard via loose type juggling (the string `"4 AND SLEEP(5)"` compares equal to integer `4`), reaching an unquoted `UPDATE wp_cs_total_dadosextras SET metodo=$metodo, ...` query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the target server to be running PHP < 8.0.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

SQL injection en parámetro POST sin autenticación (AV:N, PR:N, UI:N). Acceso a datos sensibles (C:H) y potencial manipulación de BD via UNION SELECT o UPDATE; loose type juggling en PHP <8.0 bypass la validación.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
