CVE-2025-52040

8.2 HIGH

📋 TL;DR

This SQL injection vulnerability in Frappe ERPNext allows attackers to execute arbitrary SQL queries through the blanket_order_type parameter, potentially extracting all database information. It affects organizations running vulnerable versions of ERPNext, exposing sensitive business data.

💻 Affected Systems

Products:
  • Frappe ERPNext
Versions: 15.57.5 and earlier versions with vulnerable code
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: Any deployment using the get_blanket_orders() function is vulnerable

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including customer data, financial records, user credentials, and business intelligence leading to data breach, regulatory penalties, and operational disruption.

🟠

Likely Case

Extraction of sensitive business data, customer information, and potentially credential harvesting leading to further system compromise.

🟢

If Mitigated

Limited impact with proper input validation and database permissions restricting query execution scope.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

SQL injection requires access to the vulnerable endpoint but is straightforward to exploit

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 15.57.6 or later

Vendor Advisory: https://github.com/frappe/erpnext/pull/49192/commits/1db135262d9474411ef54e3367d24bb169d2503e

Restart Required: Yes

Instructions:

1. Update to ERPNext version 15.57.6 or later. 2. Apply the patch from the GitHub commit. 3. Restart the application server. 4. Verify the fix by testing the vulnerable endpoint.

🔧 Temporary Workarounds

Input Validation Filter

all

Add parameter validation to reject malicious SQL injection attempts

# Add input validation in application code before passing to get_blanket_orders()

Database Permission Restriction

all

Limit database user permissions to read-only for application accounts

GRANT SELECT ON database.* TO 'app_user'@'localhost';
REVOKE INSERT, UPDATE, DELETE, DROP, CREATE ON database.* FROM 'app_user'@'localhost';

🧯 If You Can't Patch

  • Implement WAF rules to block SQL injection patterns in blanket_order_type parameter
  • Restrict network access to ERPNext application to trusted IPs only

🔍 How to Verify

Check if Vulnerable:

Test the vulnerable endpoint with SQL injection payloads in blanket_order_type parameter and observe database errors or unexpected data returns

Check Version:

bench version

Verify Fix Applied:

Attempt SQL injection after patch and confirm parameterized queries prevent execution

📡 Detection & Monitoring

Log Indicators:

  • Unusual database queries from application layer
  • SQL syntax errors in application logs
  • Multiple failed login attempts following unusual queries

Network Indicators:

  • Unusual database connection patterns
  • Large data transfers from database server

SIEM Query:

source="erpnext.log" AND ("SQL" OR "database error" OR "syntax error") AND "blanket_order_type"
