CVE-2025-0473

Estado: AnalizadaAlta (7.5)—

Vulnerability in the PMB platform that allows an attacker to persist temporary files on the server, affecting versions 4.0.10 and above. This vulnerability exists in the file upload functionality on the ‘/pmb/authorities/import/iimport_authorities’ endpoint. When a file is uploaded via this resource, the server will create a temporary file that will be deleted after the client sends a POST request to ‘/pmb/authorities/import/iimport_authorities’. This workflow is automated by the web client, however an attacker can trap and launch the second POST request to prevent the temporary file from being deleted.

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:N/UI:N indica explotación remota sin autenticación (T1190). El atacante persiste archivos temporales en el servidor, logrando lectura de datos almacenados (CWE-459, integridad de flujo de archivos).

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.
