CVE-2025-34163
Dongsheng Logistics Software exposes an unauthenticated endpoint at /CommMng/Print/UploadMailFile that fails to enforce proper file type validation and access control. An attacker can upload arbitrary files, including executable scripts such as .ashx, via a crafted multipart/form-data POST request. This allows remote code execution on the server, potentially leading to full system compromise. The vulnerability is presumed to affect builds released prior to July 2025 and is remediated in newer versions of the product, though the exact affected range remains undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-07-23 UTC.

"value": "Dongsheng Logistics Software expone un endpoint no autenticado en /CommMng/Print/UploadMailFile que falla en aplicar una validación adecuada del tipo de archivo y control de acceso. Un atacante puede cargar archivos arbitrarios, incluyendo scripts ejecutables como .ashx, a través de una solicitud POST multipart/form-data manipulada. Esto permite la ejecución remota de código en el servidor, lo que podría llevar a un compromiso total del sistema. La vulnerabilidad se presume que afecta a las compilaciones lanzadas antes de julio de 2025 y se dice que está remediada en versiones más nuevas del producto, aunque el rango exacto afectado permanece indefinido. La evidencia de explotación fue observada por primera vez por la Shadowserver Foundation el 23-07-2025 UTC."
