CVE 描述
In Kura versions <= 5.6.2, the "Command" file-upload handler at `POST /admin/denali/file/command` extracts a client-supplied ZIP archive into the configured `command.working.directory`. The path-containment check `validateFileName()` compares canonical paths with `String.startsWith()` without appending a trailing path separator, so an entry that canonicalises to a sibling directory sharing the same string prefix (e.g. `/tmpevil/x` when the intended directory is `/tmp`) is accepted. The handler then calls `parent.mkdirs()` and `new FileOutputStream(newFile)`, creating directories and writing attacker-controlled bytes outside the intended extraction root.
The command service is disabled by default since Kura 4.0.0 [1]. The issue does not apply when the command service is disabled. The caller must be authenticated with `rest.command` permission.

|---|---|---|
| Improper Limitation of a Pathname to a Restricted Directory The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |
