| Package Name | Ecosystem | Vulnerable Versions | First Patched Version |
|---|---|---|---|
| io.metersphere:metersphere | maven | < 2.5.1 | 2.5.1 |
The vulnerability stems from FileUtils.createFile() accepting arbitrary file paths without sanitization. The function: 1) Deletes existing files at the given path 2) Creates parent directories recursively 3) Writes file bytes to the path. Without validation of the filePath parameter, attackers can use sequences like '../../' to write files outside intended directories. The patch in v2.5.1 adds filename validation, confirming this was the vulnerable entry point. The code structure and vulnerability description directly implicate this function as the vulnerable component.
