CVE-2024-0483: Jifeer Taokeyun SQL Injection Vulnerability

CVE-2024-0483 Overview

A critical SQL injection vulnerability has been identified in Taokeyun versions up to 1.0.5. This vulnerability affects the index function within the file application/index/controller/app/Task.php, which is part of the HTTP POST Request Handler component. The vulnerability stems from improper handling of the cid argument, allowing attackers to inject malicious SQL queries remotely without authentication.

Critical Impact

Unauthenticated remote attackers can execute arbitrary SQL commands against the backend database, potentially leading to complete database compromise, data exfiltration, and unauthorized system access.

Affected Products

• Jifeer Taokeyun versions up to and including 1.0.5

Technical Details for CVE-2024-0483

Vulnerability Analysis

This SQL injection vulnerability exists in the Taokeyun e-commerce platform's task management controller. The vulnerable component fails to properly sanitize user-supplied input in the cid parameter before incorporating it into SQL queries. Because the vulnerability is accessible via HTTP POST requests without authentication requirements, any remote attacker can exploit this flaw to manipulate database queries.

The impact of successful exploitation is severe, as attackers gain the ability to read, modify, or delete database contents. In typical SQL injection scenarios of this nature, attackers may also escalate to execute operating system commands depending on the database configuration and privileges.

Root Cause

The root cause of this vulnerability is the lack of input validation and parameterized queries in the index function of application/index/controller/app/Task.php. The cid argument is directly concatenated or interpolated into SQL statements without proper escaping or prepared statement usage, creating a classic SQL injection attack surface. This represents a violation of secure coding practices where user input should never be trusted and must always be sanitized before database operations.

Attack Vector

The attack is network-based and can be initiated remotely through crafted HTTP POST requests targeting the vulnerable Task controller endpoint. The attacker manipulates the cid parameter value to include SQL metacharacters and injection payloads that alter the intended query logic. Since no authentication is required, the attack complexity is low and can be automated for mass exploitation.

The vulnerability allows for various SQL injection techniques including UNION-based injection for data extraction, boolean-based blind injection for inference attacks, and potentially stacked queries depending on the database driver configuration. For detailed technical analysis, refer to the Security Analysis Note and VulDB Entry #250588.

Detection Methods for CVE-2024-0483

Indicators of Compromise

• Unusual HTTP POST requests to /index/controller/app/Task.php endpoints containing SQL syntax in the cid parameter
• Database error messages or anomalies in application logs indicating SQL syntax errors
• Unexpected database queries containing UNION SELECT, OR 1=1, or other SQL injection patterns
• Signs of data exfiltration or unauthorized database access in audit logs

Detection Strategies

• Deploy Web Application Firewalls (WAF) with SQL injection detection rules to monitor and block malicious POST requests
• Implement database activity monitoring to detect anomalous query patterns targeting the Task controller
• Configure intrusion detection systems (IDS) to alert on HTTP requests containing common SQL injection payloads in POST data
• Review web server access logs for requests to the vulnerable endpoint with suspicious parameter values

Monitoring Recommendations

• Enable detailed logging for the Taokeyun application, particularly for the Task controller component
• Monitor database query logs for statements originating from the vulnerable index function
• Set up alerts for repeated failed or unusual queries that may indicate exploitation attempts
• Implement real-time monitoring of network traffic for POST requests targeting known vulnerable paths

How to Mitigate CVE-2024-0483

Immediate Actions Required

• Upgrade Taokeyun to a patched version beyond 1.0.5 if available from the vendor
• Implement input validation and parameterized queries for the cid parameter in the affected controller
• Deploy a Web Application Firewall with SQL injection protection as an interim mitigation measure
• Restrict network access to the application to trusted IP ranges where possible

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations using affected versions of Taokeyun should contact Jifeer for remediation guidance or consider implementing the workarounds below until a patch is released. Monitor the VulDB advisory for updates.

Workarounds

• Implement application-level input validation to sanitize the cid parameter, rejecting any non-numeric characters
• Use a Web Application Firewall to filter and block requests containing SQL injection patterns
• Modify the vulnerable Task.php file to use prepared statements with parameterized queries
• Restrict database user privileges to minimum required permissions to limit the impact of successful exploitation
• Consider temporarily disabling the vulnerable endpoint if it is not business-critical
