Bug ID: 54599
Summary: DataSource password is exposed to applications via
toString method
Product: Tomcat Modules
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: P2
Component: jdbc-pool
Assignee: [email protected]
Reporter: [email protected]
Classification: Unclassified
On the server side, create a DataSource using
"org.apache.tomcat.jdbc.pool.DataSourceFactory".
Ex:
<Resource auth="Container"
description=""
name="jdbc/testTomcatJdbc"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
type="javax.sql.DataSource"
username="sa"
password="super-secret"
driverClassName="org.h2.Driver"
url="jdbc:h2:mem:test"
minIdle="1"
initialSize="1" />
In a web application, create a JSP file, add the following:
<%@ page import="javax.naming.*" session="false" %>
<!DOCTYPE HTML>
<html>
<head>
<title>Display Password!</title>
</head>
<body>
<h1>toString for Tomcat JDBC</h1>
<%
dataSource = (javax.sql.DataSource)
ctx.lookup("java:/comp/env/jdbc/testTomcatJdbc");
out.println("<p>" + dataSource.toString() + "</p>");
%>
</body>
</html>
Access the JSP in your browser. The output from toString on the DataSource
will display the password that was configured in the <Resource/> tag.
Example Output:
toString for Tomcat JDBC
org.apache.tomcat.jdbc.pool.DataSource@75cae120{ConnectionPool[defaultAutoCommit=null;
