CVE-2022-26285
📋 TL;DR
Simple Subscription Website v1.0 contains a SQL injection vulnerability in the apply endpoint's id parameter that allows attackers to execute arbitrary SQL commands. This enables database dumping and potentially complete system compromise. Anyone running this specific software version is affected.
💻 Affected Systems
- Simple Subscription Website
📦 What is this software?
Simple Client Management System by Simple Client Management System Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive user data, authentication credentials, and potential remote code execution leading to full system takeover.
Likely Case
Database information disclosure including user credentials, personal information, and subscription data that could lead to account takeover and data theft.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data reading from specific tables.
🎯 Exploit Status
Public exploit script available on GitHub demonstrates SQL injection via HTTP requests to the apply endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with proper input validation and parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests to the apply endpoint.
Input Validation Filter
allImplement server-side input validation to restrict id parameter to expected numeric values only.
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the /apply endpoint with SQL injection payloads in the id parameter and observe database errors or unexpected responses.Check Version:
Check application version in admin panel or configuration files.Verify Fix Applied:
Attempt SQL injection attacks after implementing fixes and verify they are blocked or produce expected error responses.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in URL parameters
- Multiple failed database queries from single IP
- Database error messages in application logs
Network Indicators:
- HTTP requests to /apply endpoint with SQL keywords in parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri_path="/apply" AND (param_id CONTAINS "UNION" OR param_id CONTAINS "SELECT" OR param_id CONTAINS "--")
