Aayush created HDDS-2110:
----------------------------
Summary: Arbitrary File Download
Key: HDDS-2110
URL: https://issues.apache.org/jira/browse/HDDS-2110
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Native
Reporter: Aayush
The LOC 324 in the file
[ProfileServlet.java|https://github.com/apache/hadoop/blob/217bdbd940a96986df3b96899b43caae2b5a9ed2/hadoop-hdds/framework/src/main/java/org/apache/hadoop/hdds/server/ProfileServlet.java]
is prone to an arbitrary file download:-
{code:java}
protected void doGetDownload(String fileName, final HttpServletRequest req,
final HttpServletResponse resp) throws IOException {
File requestedFile =
ProfileServlet.OUTPUT_DIR.resolve(fileName).toAbsolutePath().toFile();{code}
As the String fileName is directly considered as the requested file.
Which is called at LOC 180 with HTTP request directly passed:-
{code:java}
if (req.getParameter("file") != null) {
doGetDownload(req.getParameter("file"), req, resp);
return;
}
{code}
