CVE-2026-0522

Description

A local file inclusion vulnerability in the upload/download flow of the VertiGIS FM application allows authenticated attackers to read arbitrary files from the server by manipulating a file's path during its upload. When the file is subsequently downloaded, the file in the attacker controlled path is returned. Due to the application's ASP.NET architecture, this could potentially lead to remote code execution when the "web.config" file is obtained. Furthermore, the application resolves UNC paths which may enable NTLM-relaying attacks. This issue affects VertiGIS FM: 10.5.00119 (0d29d428).
