CVE-2025-41714 | BDVDB-2026-293267 Detail

WelotecSmartEMS Web Application

Description#

The upload endpoint insufficiently validates the 'Upload-Key' request header. By supplying path traversal sequences, an authenticated attacker can cause the server to create upload-related artifacts outside the intended storage location. In certain configurations this enables arbitrary file write and may be leveraged to achieve remote code execution.

Impact#

Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact high. Attack vector: network.

Weaknesses#
