             Summary: A potential security issue in org.apache.hadoop.hbase.http.log.LogLevel.java
                 Key: HBASE-20339
                 URL: https://issues.apache.org/jira/browse/HBASE-20339
             Project: HBase
          Issue Type: Bug
          Components: hbase
    Affects Versions: 2.0.0-beta-2
            Reporter: andy zhou


Our program analyzer have detected a potential security issue as follows 
{code:java}
PrintWriter out = ServletUtil.initHTML(response, "Log Level");
String logName = ServletUtil.getParameter(request, "log");
String level = ServletUtil.getParameter(request, "level");

if (logName != null) {
   out.println("<br /><hr /><h3>Results</h3>");
   out.println(MARKER
        + "Submitted Log Name: <b>" + logName + "</b><br />");
  ...
}{code}
Above is the code piece. Seems that the log name is directly collected from the web request, and only whether the data is null is checked. So an attacker may provide a logName with a piece of injected code leading to cross-site attacks. And besides, the variable "level" may also have such vulnerability.
