CVE-2022-44151
📋 TL;DR
CVE-2022-44151 is a critical SQL injection vulnerability in Simple Inventory Management System v1.0's login.php endpoint that allows attackers to execute arbitrary SQL commands. This affects all users running the vulnerable version, potentially leading to complete system compromise. Attackers can bypass authentication, extract sensitive data, or execute arbitrary code on the database server.
💻 Affected Systems
- Simple Inventory Management System
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover: attackers can extract all database contents (including credentials), execute arbitrary commands on the database server, and potentially achieve remote code execution on the underlying system.
Likely Case
Authentication bypass leading to unauthorized access, data exfiltration of inventory and user data, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database server access from external sources.
🎯 Exploit Status
Exploit code is publicly available and requires minimal technical skill to execute. The vulnerability is in the login form which is typically publicly accessible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Replace vulnerable login.php with secure version using parameterized queries
2. Implement input validation for all user inputs
3. Update to a maintained version if available
4. Review and sanitize all database queries in the application
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the login endpoint
Input Validation Filter
allAdd input validation to filter SQL metacharacters from login parameters
// PHP example: filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation
- Implement network segmentation to restrict database server access only to the application server
🔍 How to Verify
Check if Vulnerable:
Test the login.php endpoint with SQL injection payloads like: ' OR '1'='1 in username/password fieldsCheck Version:
Check the application's version file or configuration, typically in README or config.phpVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or properly handled without database errors📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL metacharacters
- Database error messages in application logs
- Unusual database queries from application user
Network Indicators:
- SQL injection patterns in HTTP POST requests to /ims/login.php
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/ims/login.php" AND (message="*sql*" OR message="*database*" OR message="*syntax*" OR message="*union*" OR message="*select*" OR message="*or 1=1*")
