CVE-2024-11998
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary SQL commands via the 'id' parameter in the /visualizer-forneccedor.chp file in Farmacia 1.0. Attackers can potentially read, modify, or delete database content. Anyone running Farmacia 1.0 with this file accessible is affected.
💻 Affected Systems
- Farmacia
📦 What is this software?
Farmacia by Farmacia Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, or deletion; potential authentication bypass leading to administrative access; possible remote code execution if database functions allow it.
Likely Case
Data extraction from the database, including sensitive information like user credentials, personal data, or business records.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
The exploit is publicly available on GitHub and requires minimal technical skill to execute against vulnerable systems.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch is available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize the 'id' parameter before processing.
# Example PHP input validation
$id = filter_var($_GET['id'], FILTER_VALIDATE_INT);
if ($id === false) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests.
# Example mod_security rule
SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only trusted IP addresses.
- Implement database user with minimal privileges (read-only if possible) for the application connection.
🔍 How to Verify
Check if Vulnerable:
Test the /visualizer-forneccedor.chp endpoint with SQL injection payloads in the 'id' parameter (e.g., id=1' OR '1'='1). Monitor for database errors or unexpected responses.Check Version:
Check the application version through its interface or configuration files. For Farmacia, review the software documentation or admin panel.Verify Fix Applied:
After implementing fixes, retest with the same payloads to ensure they are blocked or sanitized properly.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to /visualizer-forneccedor.chp with suspicious 'id' parameters
- Database query errors containing SQL syntax
Network Indicators:
- HTTP requests with SQL keywords (e.g., UNION, SELECT, OR) in the 'id' parameter
- Abnormal traffic patterns to the vulnerable endpoint
SIEM Query:
Example: source="web_logs" AND uri="/visualizer-forneccedor.chp" AND (query_string="*id=*OR*" OR query_string="*id=*UNION*" OR query_string="*id=*SELECT*")
