>                 Key: HDFS-6368
>                 URL: https://issues.apache.org/jira/browse/HDFS-6368
>             Project: Hadoop HDFS
>          Issue Type: Bug
>            Reporter: Ted Yu
>            Priority: Minor
>
> Currently only null check is performed:
> {code}
>           if (fsImageName == null) {
>             throw new IOException("No filename header provided by server");
>           }
>           newLocalPaths.add(new File(localPath, fsImageName));
> {code}
> Value of fsImageName, obtained from HttpURLConnection header, may be tainted.
> This may allow an attacker to access, modify, or test the existence of critical or sensitive files.
