Dear list,

I am working on some Java code reviews and was looking for injection vectors
that may apply on it.

Take for example the following code:

---------------------
public User getUsers(String userID) {
...
NamedQuery query = new NamedQuery(User.class, "user.view.by.id");
Map parameters = new HashMap();
parameters.put("userid", userID);
query.setParameters(parameters);
List list = Repository.select(query);
...
}
----------------------

That piece of code interacts with Hibernate to get a list of user objects
with that ID from a relational DB. Here is the extract of the HBM mapping
file:

--------------------
<property name="userID" type="string" length="15" column="USER_ID"/>
....
<query name="user.view.by.id"><![CDATA[
from com.test.user as userX
where userID = :userid
]]>
</query>
--------------------

I am wondering if this represents vulnerable code, exploited by, for
example, calling getUsers("' or '1'='1") or something of the sort.

Second, suppose the application interacts with an LDAP server, using the
following code:

------------------------------------
public boolean checkUser(String userID) {

            boolean result = false;
            Attributes srchAttrs = new BasicAttributes(true);
            String [] resAttrsID = {"uid"};

            searchAttrs.put("uid", userID);
            Enumeration srchResults = null;

            srchResults = ctx.search(LDAP.getBranch(), srchAttrs,
resAttrsID);
            if((srchResults != null) && (srchResults.hasMoreElements() ==
true))
                result = true;

            result = false;

}
------------------------------------

Is this function vulnerable to LDAP Injection?

Looking foward to reading your opinions....

Andy.
