CVE-2025-34163Known exploitationNetwork attack vector

Unauthenticated code execution via unrestricted script upload

Published Aug 27, 2025 · Updated Aug 4, 2026

Unrestricted file upload in Dongsheng Logistics Software pre-July 2025 builds allows remote attackers to execute code without authentication. The /CommMng/Print/UploadMailFile endpoint accepts multipart uploads without enforcing access control or rejecting executable file types such as .ashx. Network access to the endpoint is sufficient to place a malicious server-side script and execute it with the application's privileges.
