CVE-2019-25366
📋 TL;DR
CVE-2019-25366 is an SQL injection vulnerability in microASP Portal+ CMS that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code into the explode_tree parameter. This enables attackers to extract sensitive database information like database names, potentially leading to full database compromise. All users running vulnerable versions of microASP Portal+ CMS are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including extraction of all sensitive data (user credentials, personal information, configuration secrets), potential remote code execution via database functions, and full system takeover.
Likely Case
Database information disclosure including database names, table structures, and potentially sensitive application data stored in the database.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection, though the vulnerable code path remains present.
🎯 Exploit Status
Exploit code is publicly available on Exploit-DB (ID: 46799) and requires minimal technical skill to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specifically documented in public sources
Vendor Advisory: http://www.microasp.it/
Restart Required: No
Instructions:
1. Contact microASP for patched version 2. Replace vulnerable pagina.phtml file 3. Implement input validation for explode_tree parameter 4. Use parameterized queries for database operations
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting pagina.phtml with explode_tree parameter
Input Validation Filter
allAdd server-side validation to reject malicious characters in explode_tree parameter
🧯 If You Can't Patch
- Block external access to pagina.phtml via network firewall or web server configuration
- Implement strict input validation and parameterized queries in the application code
🔍 How to Verify
Check if Vulnerable:
Send crafted request to /pagina.phtml with SQL injection payload in explode_tree parameter and check for database error responses or information disclosureCheck Version:
Check CMS version in administration panel or configuration filesVerify Fix Applied:
Test the same exploit payload after patching - should return generic error or no database information📡 Detection & Monitoring
Log Indicators:
- HTTP requests to pagina.phtml containing SQL keywords (SELECT, UNION, CONCAT, EXTRACTVALUE)
- Database error messages in web server logs
- Unusual parameter values in explode_tree parameter
Network Indicators:
- HTTP POST/GET requests to pagina.phtml with SQL injection patterns
- Multiple rapid requests to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/pagina.phtml" AND (param="explode_tree" AND value MATCHES "(?i)(SELECT|UNION|CONCAT|EXTRACTVALUE)")
