CVE-2025-58745

Estado: AnalizadaAlta (8.8)—

WeGIA is a Web manager for charitable institutions. The fix for CVE-2025-22133 was not enough to remediate the arbitrary file upload vulnerability. The WeGIA only check MIME types for Excel files at endpoint `/html/socio/sistema/controller/controla_xlsx.php`, which can be bypassed by using magic bytes of Excel file in a PHP file. As a result, attacker can upload webshell to the server for remote code execution. Version 3.4.11 contains an updated fix.

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.

AV:N/PR:L requiere red y privilegios; bypass de MIME mediante magic bytes permite upload de webshell PHP (T1505.003) y ejecución de código remoto (T1059). Fix incompleto de CVE anterior sustenta la vulnerabilidad.

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.
