CVE-2025-58439: Frappe ERPNext SQL Injection Vulnerability

CVE-2025-58439 Overview

CVE-2025-58439 is a SQL Injection vulnerability affecting Frappe ERPNext, a free and open source Enterprise Resource Planning (ERP) tool. The vulnerability exists due to insufficient validation of user-supplied parameters, leaving certain API endpoints vulnerable to error-based SQL Injection attacks. Attackers can exploit this flaw to extract sensitive information from the underlying database, including system version details and potentially other stored data.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to extract sensitive data from ERPNext databases without requiring user interaction, potentially exposing business-critical information stored in the ERP system.

Affected Products

• Frappe ERPNext versions below 14.89.2
• Frappe ERPNext versions 15.0.0 through 15.75.1
• All deployments using vulnerable API endpoints without input validation

Technical Details for CVE-2025-58439

Vulnerability Analysis

This vulnerability is classified as CWE-89 (SQL Injection), a critical class of web application security flaws where attacker-controlled input is incorporated into SQL queries without proper sanitization. In the case of Frappe ERPNext, certain API endpoints accept user parameters that are directly used in database queries, allowing attackers to manipulate the SQL logic through carefully crafted input.

The error-based SQL Injection variant observed in this vulnerability leverages database error messages to extract information. When an attacker submits malformed SQL syntax, the application returns error responses that reveal database structure, version information, and potentially sensitive data stored in the system.

Enterprise Resource Planning systems like ERPNext typically store highly sensitive business data including financial records, customer information, inventory details, and employee data. Successful exploitation of this vulnerability could lead to unauthorized access to confidential business intelligence and regulatory compliance violations.

Root Cause

The root cause of CVE-2025-58439 is the lack of proper input validation and parameterization for user-supplied data in vulnerable API endpoints. Instead of using prepared statements or parameterized queries, the application constructs SQL queries by directly concatenating user input, creating an injection point that attackers can exploit.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker can craft malicious HTTP requests to vulnerable endpoints, injecting SQL syntax into parameter values. The attack is classified as having network-based attack vector with low complexity, meaning it can be exploited remotely with minimal technical barriers.

The error-based injection technique allows attackers to systematically extract database contents by observing differences in application responses. Information such as database version, table names, column structures, and actual data values can be extracted through this method.

Detection Methods for CVE-2025-58439

Indicators of Compromise

• Unusual SQL syntax patterns in web server access logs targeting ERPNext API endpoints
• Database error messages appearing in application logs or HTTP responses
• Unexpected or malformed query parameters containing SQL keywords like SELECT, UNION, OR, and comment sequences
• Increased database query errors or timeout events correlating with external requests

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block common SQL Injection patterns in HTTP requests
• Enable detailed logging for ERPNext API endpoints and monitor for suspicious parameter values
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access attempts
• Use intrusion detection systems (IDS) with SQL Injection signature rules targeting your ERPNext deployment

Monitoring Recommendations

• Monitor web server logs for requests containing SQL metacharacters and keywords in query parameters
• Set up alerts for database errors that may indicate injection attempts
• Track access patterns to sensitive ERPNext endpoints for anomalous behavior
• Review application logs for error messages that could indicate successful or attempted SQL Injection

How to Mitigate CVE-2025-58439

Immediate Actions Required

• Upgrade Frappe ERPNext to version 14.89.2 or later for the 14.x branch
• Upgrade Frappe ERPNext to version 15.76.0 or later for the 15.x branch
• Review database audit logs for any signs of unauthorized access or data extraction
• Implement web application firewall rules to filter SQL Injection attempts as a defense-in-depth measure

Patch Information

Frappe has released security patches addressing this vulnerability. The fixes are available in versions 14.89.2 and 15.76.0. Technical details of the patches can be found in GitHub Pull Request #49219 and GitHub Pull Request #49220. For complete vulnerability details, refer to the GitHub Security Advisory GHSA-fvjw-5w9q-6v39.

Workarounds

• Deploy a web application firewall (WAF) with SQL Injection detection rules in front of ERPNext
• Restrict network access to ERPNext API endpoints to trusted IP addresses where feasible
• Enable verbose logging and monitoring to detect exploitation attempts while preparing for patching
• Consider temporarily disabling or restricting access to non-essential API endpoints until the patch can be applied

# Example: Check current ERPNext version
bench version

# Upgrade ERPNext to the patched version
bench update --apps erpnext
bench migrate
