CVE-2025-34040

Estado: AplazadaCrítica (10)—

An arbitrary file upload vulnerability exists in the Zhiyuan OA platform via the wpsAssistServlet interface. The realFileType and fileId parameters are improperly validated during multipart file uploads, allowing unauthenticated attackers to upload crafted JSP files outside of intended directories using path traversal. Successful exploitation enables remote code execution as the uploaded file can be accessed and executed through the web server. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-01 UTC.

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.

Vulnerabilidad de carga de archivos sin autenticación en interfaz web (AV:N/PR:N/UI:N) que permite subir JSP con path traversal y ejecutarlos vía servidor web (web shell T1505.003), acceso a archivos del servidor (T1005) y ejecución remota de código (T1059).

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.
