CVE-2018-25191
📋 TL;DR
Facturation System 1.0 contains an SQL injection vulnerability in the editar_producto.php endpoint that allows authenticated attackers to execute arbitrary SQL queries. Attackers can extract sensitive database information including usernames, database names, and version details by injecting malicious code through the 'mod_id' parameter. This affects all installations of Facturation System 1.0 with default configurations.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation, and potential system takeover via subsequent attacks.
Likely Case
Extraction of sensitive business data, customer information, and authentication credentials from the database.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented.
🎯 Exploit Status
Public exploit available on Exploit-DB. Requires authentication but SQL injection is straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to supported software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the mod_id parameter in editar_producto.php
Modify editar_producto.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM products WHERE id = ?'); $stmt->bind_param('i', $mod_id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in POST requests to editar_producto.php
Configure WAF to block requests containing SQL keywords like UNION, SELECT, INSERT, DELETE when sent to editar_producto.php
🧯 If You Can't Patch
- Isolate the Facturation System from internet access and restrict to internal network only
- Implement strict authentication controls and monitor for suspicious database queries
🔍 How to Verify
Check if Vulnerable:
Test by sending POST request to editar_producto.php with SQL injection payload in mod_id parameter and checking for database error responses or data leakageCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Attempt SQL injection after implementing fixes and verify no database information is returned📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed authentication attempts followed by successful login
- POST requests to editar_producto.php with SQL keywords in parameters
Network Indicators:
- Unusual database connection patterns from web server
- Large data transfers from database to web application
SIEM Query:
source="web_logs" AND uri="/editar_producto.php" AND (param="mod_id" AND value MATCHES "(?i)(union|select|insert|delete|drop|--|#)")
