CVE-2024-0784: Hongmaple Octopus SQL Injection Vulnerability

CVE-2024-0784 Overview

A critical SQL injection vulnerability has been discovered in hongmaple octopus version 1.0. The vulnerability exists in the /system/role/list endpoint where improper handling of the dataScope parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion of sensitive information.

Critical Impact

This SQL injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the backend database, potentially compromising the entire application's data integrity and confidentiality.

Affected Products

• hongmaple octopus 1.0
• hongmaple octopus (rolling release versions)

Technical Details for CVE-2024-0784

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the /system/role/list endpoint in hongmaple octopus. The application fails to properly sanitize user-supplied input in the dataScope parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL statements that are executed by the database with the application's privileges.

The vulnerability can be exploited remotely without authentication, making it particularly dangerous. An attacker can leverage this flaw to extract sensitive data from the database, bypass authentication mechanisms, modify or delete data, and potentially achieve further compromise of the underlying system depending on database configurations and privileges.

The exploit details have been publicly disclosed, increasing the risk of active exploitation. Since hongmaple octopus uses a rolling release model, specific version details for patched releases are not available, making it difficult to confirm remediation status.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements in the application's database interaction layer. When user input from the dataScope parameter is directly concatenated into SQL queries without proper sanitization or escaping, it creates an injection point that attackers can exploit.

Attack Vector

The attack can be launched remotely over the network. An attacker sends a crafted HTTP request to the /system/role/list endpoint with a malicious dataScope parameter value containing SQL injection payloads. The vulnerable application processes this input without adequate validation, allowing the injected SQL commands to execute against the database.

Typical attack scenarios include:

• Union-based injection to extract data from other tables
• Boolean-based blind injection to enumerate database contents
• Time-based blind injection when direct output is not visible
• Stacked queries (if supported) to execute arbitrary SQL commands

For detailed technical information about this vulnerability, refer to the GitHub Report Document and VulDB Entry #251700.

Detection Methods for CVE-2024-0784

Indicators of Compromise

• Unusual or malformed requests to /system/role/list endpoint containing SQL syntax in the dataScope parameter
• Database error messages in application logs indicating SQL syntax errors
• Abnormal database query patterns including UNION SELECT, OR 1=1, WAITFOR DELAY, or other SQL injection signatures
• Unexpected data access or exfiltration from database tables

Detection Strategies

• Deploy web application firewalls (WAF) with SQL injection detection rules targeting the /system/role/list endpoint
• Implement database activity monitoring to detect anomalous query patterns
• Configure application logging to capture and alert on requests with suspicious parameter values
• Use intrusion detection systems (IDS) with signatures for common SQL injection payloads

Monitoring Recommendations

• Monitor HTTP request logs for patterns indicating SQL injection attempts in the dataScope parameter
• Enable database audit logging to track all queries executed against the database
• Set up alerting for database errors that may indicate injection attempts
• Review access logs regularly for unauthorized access to sensitive database tables

How to Mitigate CVE-2024-0784

Immediate Actions Required

• Restrict network access to the affected /system/role/list endpoint until a patch is available
• Deploy a web application firewall with rules to block SQL injection attempts
• Implement input validation at the application perimeter to filter malicious requests
• Monitor for exploitation attempts and review database logs for signs of compromise

Patch Information

As hongmaple octopus uses a rolling release model for continuous delivery, no specific version details for patched releases are available. Check the official hongmaple octopus repository or contact the vendor for the latest security updates. Additional vulnerability details can be found in the VulDB CTIID #251700 entry.

Workarounds

• Implement strict input validation on the dataScope parameter to allow only expected values
• Use prepared statements or parameterized queries if modifying the application code
• Apply network-level restrictions to limit access to the vulnerable endpoint
• Consider temporarily disabling the /system/role/list functionality if not critical to operations
