## What is CVE-2025-34163?

CVE-2025-34163 is a critical vulnerability in Qingdao Dongsheng Weiye Software Co., Ltd. Dongsheng Logistics Software, published on 27 Aug 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)
