📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to theft of sensitive banking information, financial fraud, unauthorized locker access, and potential system takeover.
Likely Case
Data exfiltration of sensitive banking records, unauthorized access to locker information, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or minimal data exposure.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub. Attack requires access to the vulnerable endpoint but may not require authentication depending on application configuration.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
Check vendor website for security updates. If no patch available, implement workarounds immediately.
🔧 Temporary Workarounds
Input Validation and Sanitization
PHPImplement strict input validation and parameterized queries for the lockersize parameter in edit-locker.php
Implement prepared statements: $stmt = $conn->prepare('UPDATE lockers SET size = ? WHERE id = ?'); $stmt->bind_param('si', $lockersize, $ltid);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests containing SQL keywords (UNION, SELECT, INSERT, etc.) in lockersize parameter to /edit-locker.php
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from critical infrastructure
- Deploy database monitoring to detect unusual query patterns and access attempts
🔍 How to Verify
Check if Vulnerable:
Test the /edit-locker.php endpoint with SQL injection payloads in the lockersize parameter and observe database errors or unexpected behaviorCheck Version:
Check application documentation or source code for version informationVerify Fix Applied:
Attempt SQL injection attacks against the patched endpoint and verify they are properly rejected without database errors📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns from web server logs
- Multiple failed SQL queries from single IP addresses
- Requests to /edit-locker.php with suspicious parameter values
Network Indicators:
- Unusual traffic patterns to the vulnerable endpoint
- SQL error messages in HTTP responses
SIEM Query:
source="web_logs" AND uri="/edit-locker.php" AND (param="lockersize" AND value MATCHES "(?i)(union|select|insert|delete|drop|--|#)")
