Welcome to another edition of our in-depth analysis of various cybersecurity vulnerabilities. Today, we are going to discuss CVE-2024-24323, which concerns a SQL injection vulnerability in the popular linlinjava litemall software, version 1.8.. For those new to SQL injection attacks, this vulnerability enables a remote attacker to obtain sensitive information by manipulating the "nickname," "consignee," "orderSN," or "orderStatusArray" parameters of the AdminOrdercontroller.java component.

The linlinjava litemall suite

Before diving into the vulnerability details, let's briefly discuss the software affected by it. linlinjava litemall is a highly popular full stack Java-based open source e-commerce platform utilizing Spring Boot and Vue.js. With features such as RESTful APIs, plugins, and themes, it has drawn the attention of aspiring developers and businesses looking to set up an online presence rapidly. The GitHub repository can be found at https://github.com/linlinjava/litemall.

Breaking down the vulnerability

According to the original report, the vulnerability stems from improper handling of input parameters within the AdminOrdercontroller.java component. Specifically, the "nickname," "consignee," "orderSN," and "orderStatusArray" parameters are susceptible to SQL injection, allowing an attacker to manipulate the database query and obtain sensitive information.

Here's a code snippet of the vulnerable component

@Autowired
private LitemallOrderService orderService;
...
@RequestMapping("/list")
public Object list(Integer userId, String orderSn,
 LinearOffsetDateTime start_time, LinearOffsetDateTime end_time,
  String consignee, Integer page, Integer limit, String sort, String order) {
  
  List<LitemallOrder> orderList = orderService.querySelective(userId,  orderSn, start_time, end_time, consignee, page, limit, sort, order);
  int total = PageInfo.of(orderList).getTotal();
  ...
}

Based on the code above, it's clear that the application does not perform any sort of input validation or sanitization on the parameters (nickname, consignee, orderSN, and orderStatusArray). As a result, these parameters become potentially exploitable via SQL injection attacks.

Exploiting the vulnerability: An example

Since the vulnerable component allows the attacker to manipulate SQL queries, an attacker can craft a malicious input to exfiltrate sensitive data from the database. Let's consider a simplified example. An attacker might send a malicious payload like the following through the "orderSN" parameter:

orderSN=test' UNION SELECT id,username,password FROM users--

This payload will essentially modify the SQL query such that it returns sensitive user information, including their usernames and passwords. While our example is quite straightforward, SQL injection attacks can be far more sophisticated and challenging to detect.

Mitigation and prevention

Updating to the latest version of the software is the best course of action to mitigate this vulnerability. However, other general practices to prevent SQL injection attacks include using prepared statements, parameterized queries, and input validation to ensure that user inputs adhere to the expected data format. Furthermore, employing least privilege principles and limiting the permissions of database users can help minimize the impact of a potential SQL injection attack.

Wrapping up

In conclusion, CVE-2024-24323 is a critical vulnerability that affects an otherwise robust and popular e-commerce platform. By gaining a deep understanding of the vulnerability and its potential exploitation methods, developers and businesses can take the necessary steps to safeguard the affected software and enhance their overall security posture. Stay vigilant and proactive, and always keep your software up-to-date!
