Advisory Information:
================================================
JSPMyAdmin 1.1 SQL Injection, CSRF & XSS Vulnerabilities


SQL Injection
CSRF
XSS



Vulnerability Details:
=====================

SQL Injection:
deletedata.jsp is supposed to delete 1 field per query, yet we can control
the SQL and build an OR condition.
Problem is application uses concatenated user input to build SQL statements
even though paramaterized queries are used.

In deletedata.jsp we find the following code:

con.prepareStatement("DELETE FROM " + table + " WHERE "+ field + "='" + val
+"'");

So expected SQL to be run is this deleting 1 record.

e.g.
http://localhost:8081/JSPMyAdmin/deletedata.jsp?db=test&table=email&field=CATID&val=7

But the SQL Injection vulnerability lets us instead drop all fields using
an SQL 'OR' statement.

e.g.
http://localhost:8081/JSPMyAdmin/deletedata.jsp?db=test&table=email&field=CATID
or
'field'='NAME'

*************************************************************************************************


CSRF:
We can drop any database by sending victim malicious linx as there is no
CSRF token used.
*****************************************************************************************


XSS:

There is zero user input checks allowing remote attackers to execute
arbitrary scripts in the
context of an authenticated user's browser session.
