CVE-2026-1422
📋 TL;DR
This SQL injection vulnerability in code-projects Online Examination System 1.0 allows attackers to manipulate database queries through the login page's User parameter. Attackers can potentially bypass authentication, extract sensitive data, or execute arbitrary SQL commands. Any organization using this specific version of the software is affected.
💻 Affected Systems
- code-projects Online Examination System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution.
Likely Case
Authentication bypass allowing unauthorized access to the examination system, data exfiltration of user credentials and exam data.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-sensitive data.
🎯 Exploit Status
Exploit details are publicly available on GitHub. SQL injection via login page requires no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for security updates
2. If no patch available, implement workarounds
3. Consider replacing with alternative software
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameterized queries and input validation to /index.php login handler
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $user);
Web Application Firewall Rules
allBlock SQL injection patterns in login parameters
Add WAF rule: SecRule ARGS:User "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from web server
🔍 How to Verify
Check if Vulnerable:
Test login page with SQL injection payloads like ' OR '1'='1 in User parameterCheck Version:
Check source code or documentation for version 1.0 referencesVerify Fix Applied:
Attempt SQL injection tests after implementing parameterized queries; verify no database errors or unexpected behavior📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login attempts
- Multiple failed login attempts with SQL characters
- Database error messages in web logs
Network Indicators:
- HTTP POST requests to /index.php containing SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/index.php" AND (request_body LIKE "%OR%" OR request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%")
