| Titre | GitHub spark V 2.9.4 SparkJava External Static Files Symlink Escape Allows Local File |
|---|
| Description | An attacker who can create or influence a symbolic link inside a directory served through staticFiles.externalLocation(...) can make SparkJava disclose arbitrary local files readable by the Java process. Typical exposure patterns include applications that serve user-controlled extracted archives, build artifacts, generated documentation, or upload directories as external static files.
This is not a claim that every SparkJava static deployment is remotely exploitable. Exploitation requires an attacker-controlled symlink or equivalent filesystem state under the configured external static root. |
