Java SQL/LDAP Injections

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. _________________________________________________________________Moda para esta temporada.
