----------------------------
Summary: DOM XSS
Key: HDDS-2111
URL: https://issues.apache.org/jira/browse/HDDS-2111
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Aayush
VULNERABILITY DETAILS
There is a way to bypass anti-XSS filter for DOM XSS exploiting a
"window.location.href".
Considering a typical URL:
scheme://domain:port/path?query_string#fragment_id
Browsers encode correctly both "path" and "query_string", but not the
"fragment_id".
So if used "fragment_id" the vector is also not logged on Web Server.
VERSION
Chrome Version: 10.0.648.134 (Official Build 77917) beta
REPRODUCTION CASE
This is an index.html page:
{code:java}
<pre>aws s3api --endpoint
<script>document.write(window.location.href.replace("static/", ""))</script>
create-bucket --bucket=wordcount</pre>
{code}
The attack vector is:
index.html?#<script>alert('XSS');</script>
* PoC:
For your convenience, a minimalist PoC is located on:
