CVE-2026-100520

Estado: AplazadaAlta (8.7)—

Laranode versions before 1.2.1 contain a path traversal vulnerability in the POST /filemanager/upload-file endpoint that allows authenticated users to write arbitrary files outside their home directory. Attackers can supply directory traversal sequences in the path parameter to write PHP files into other tenants' web roots and execute code as those tenants.

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.

Servicio web remoto (upload-file) explotado por usuario autenticado para escribir PHP en raíces web ajenas y ejecutar código en otros tenants. Requiere acceso previo (PR:L).

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.
