CWE-564 SQL注入:Hibernate

SQL Injection: Hibernate

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

Using Hibernate to execute a dynamic SQL statement built with user-controlled input can allow an attacker to modify the statement's meaning or to execute arbitrary SQL commands.

可能的缓解方案

Requirements

策略:

A non-SQL style database which is not subject to this flaw may be chosen.

Architecture and Design

策略:

Follow the principle of least privilege when creating user accounts to a SQL database. Users should only have the minimum privileges necessary to use their account. If the requirements of the system indicate that a user can read and modify their own data, then limit their privileges so they cannot read/write others' data.

MIT-15 Architecture and Design

策略:

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Implementation

策略:

Implement SQL strings using prepared statements that bind variables. Prepared statements that do not bind variables can be vulnerable to attack.

Implementation

策略:

Use vigorous whitelist style checking on any user input that may be used in a SQL command. Rather than escape meta-characters, it is safest to disallow them entirely. Reason: Later use of data that have been entered in the database may neglect to escape meta-characters before use. Narrowly define the set of safe characters based on the expected value of the parameter in the request.

示例代码

The following code excerpt uses Hibernate's HQL syntax to build a dynamic query that's vulnerable to SQL injection.

bad Java

String street = getStreetFromUser();
Query query = session.createQuery("from Address a where a.street='" + street + "'");
