CVE-2026-0522Local File Inclusion in the File Upload/Download Process
High 7.4
In plain English
A high-severity security flaw in VertiGIS FM from VertiGIS. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 50% of all known vulnerabilities).
Official 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).
