path/common/down/file?filekey=/../../../../../../../../../etc/passwd
path/common/DownController.java
  • Look for GET requests to /common/down/file with a 'filekey' parameter containing path traversal sequences (e.g., /../ or ../../../../)
  • A successful exploitation returns HTTP 200 with /etc/passwd content matching root:.*:0:0: in the response body
  • JFinalCMS instances can be fingerprinted via FOFA using the body signature content="JreCms"
  • The vulnerability is unauthenticated (PR:N) and network-reachable (AV:N), meaning no credentials are required to exploit the directory traversal via the filekey parameter
  • ·The vulnerable endpoint is specifically /common/down/file and the traversal parameter is named 'filekey'; only JFinalCMS v5.0.0 is confirmed affected per the CVE
