CVE-2025-34163

CRITICAL EXPLOITED

Dongsheng Logistics Software < pre-July 2025 - Unauthenticated Arbitrary File Upload

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2025-34163 has been observed exploited in the wild (reported by VulnCheck KEV).

Description

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.
