## Overview

JeeWMS before commit 0a610e8 contains an unauthenticated path traversal vulnerability that allows remote attackers to read arbitrary files via the dbPath parameter. Attackers can send GET requests to /systemController/showOrDownByurl.do with ../ sequences in dbPath, which bypasses AuthInterceptor, to retrieve files like win.ini. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.

## Affected

- `JeeWMS >= 194f221776cfcfd838abab7107b1a8352ea2bc59 < 0a610e8178a0a1197e9c6615b58faf67c406d2bc`
