CVE-2025-15439: Daptin SQL Injection Vulnerability

CVE-2025-15439 Overview

A SQL injection vulnerability was identified in Daptin version 0.10.3. The vulnerability affects the goqu.L function within the file server/resource/resource_aggregate.go of the Aggregate API component. Through manipulation of the column, group, or order arguments, an attacker can inject malicious SQL commands. This vulnerability is remotely exploitable and a public exploit is available.

Critical Impact

Authenticated attackers can remotely exploit this SQL injection vulnerability to potentially read, modify, or delete database contents, compromising data confidentiality, integrity, and availability.

Affected Products

• Daptin version 0.10.3
• Daptin Aggregate API component
• Applications utilizing the affected goqu.L function in server/resource/resource_aggregate.go

Technical Details for CVE-2025-15439

Vulnerability Analysis

This SQL injection vulnerability exists in Daptin's Aggregate API due to improper input validation in the goqu.L function. The vulnerable code path is located in server/resource/resource_aggregate.go, where user-supplied input through the column, group, and order parameters is not adequately sanitized before being incorporated into SQL queries.

The vulnerability allows remote authenticated attackers to inject arbitrary SQL statements, potentially enabling unauthorized database access. Due to the network-accessible nature of the API and low attack complexity, exploitation requires minimal technical skill once authenticated access is obtained.

The vendor was contacted regarding this vulnerability but did not respond to the disclosure notification.

Root Cause

The root cause of this vulnerability is CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), specifically manifesting as SQL injection. The goqu.L function fails to properly sanitize or parameterize user-controlled input before constructing SQL queries. When processing aggregate API requests, the column, group, and order parameters are passed directly to the query builder without adequate validation, allowing attackers to break out of the intended query structure and inject malicious SQL commands.

Attack Vector

The attack is initiated remotely over the network against the Daptin Aggregate API. An authenticated attacker can craft malicious HTTP requests containing SQL injection payloads within the column, group, or order parameters. These parameters are processed by the vulnerable goqu.L function, which incorporates them into database queries without proper sanitization.

The exploitation mechanism involves sending specially crafted API requests to the aggregate endpoint. Technical details and proof of concept information are available through the HXLab Proof of Concept documentation.

Detection Methods for CVE-2025-15439

Indicators of Compromise

• Unusual or malformed HTTP requests to the Daptin Aggregate API endpoints containing SQL syntax in column, group, or order parameters
• Database query logs showing unexpected SQL commands, UNION statements, or comment sequences (--, /*)
• Error messages in application logs indicating SQL parsing failures or syntax errors
• Unexpected database access patterns or data exfiltration attempts

Detection Strategies

• Implement web application firewall (WAF) rules to detect common SQL injection patterns in API requests
• Monitor Aggregate API endpoint traffic for requests containing SQL keywords (SELECT, UNION, INSERT, DROP, etc.) in parameter values
• Configure database audit logging to track unusual query patterns originating from the Daptin application
• Deploy runtime application self-protection (RASP) solutions to identify SQL injection attempts in real-time

Monitoring Recommendations

• Enable detailed logging for all Aggregate API requests and review for suspicious parameter values
• Set up alerting for database queries that exceed normal complexity or access unauthorized tables
• Monitor for repeated authentication attempts followed by unusual API activity patterns
• Implement anomaly detection on API response sizes and query execution times

How to Mitigate CVE-2025-15439

Immediate Actions Required

• Restrict network access to the Daptin Aggregate API to trusted sources only
• Implement input validation and parameterized queries at the application level if possible
• Deploy a web application firewall (WAF) with SQL injection detection rules in front of the Daptin instance
• Consider disabling or restricting the Aggregate API functionality until a patch is available

Patch Information

No official patch information is currently available. The vendor was contacted regarding this vulnerability but did not respond. Organizations should monitor the VulDB entry and official Daptin channels for updates on security patches.

Additional technical details are available through the HXLab Shared Resource.

Workarounds

• Implement a reverse proxy or API gateway that validates and sanitizes the column, group, and order parameters before forwarding requests
• Use network segmentation to limit access to Daptin instances from untrusted networks
• Apply strict input validation rules at the application layer to reject requests containing SQL metacharacters
• Consider implementing database user permissions to limit the impact of potential SQL injection attacks

# Example: WAF rule configuration to block SQL injection patterns (adapt for your WAF solution)
# Block requests containing common SQL injection patterns in query parameters
# location /api/aggregate {
#     if ($args ~* "(union|select|insert|update|delete|drop|;|--|/\*)") {
#         return 403;
#     }
#     proxy_pass http://daptin_backend;
