🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch is available. Consider migrating to alternative HR software or implementing custom fixes with parameterized queries and input validation.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the /src/store/NoticeStore.php endpoint and noticeDesc parameter.
Input Validation Filter
allAdd input validation to sanitize the noticeDesc parameter before processing, rejecting suspicious SQL patterns.
🧯 If You Can't Patch
- Isolate the HR system on a separate network segment with strict firewall rules limiting access to authorized users only.
- Implement database-level protections including least privilege accounts, stored procedures, and regular monitoring of database logs for suspicious queries.
🔍 How to Verify
Check if Vulnerable:
Check if the file /src/store/NoticeStore.php exists and contains unsanitized noticeDesc parameter usage in SQL queries. Test with SQL injection payloads like ' OR '1'='1.Check Version:
Check the software version in the application's configuration files or about page; look for version 1.0.Verify Fix Applied:
Verify that all SQL queries using noticeDesc parameter are using prepared statements or proper escaping. Test with SQL injection payloads to confirm they are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs, especially containing SQL keywords like UNION, SELECT, INSERT in noticeDesc parameter
- Multiple failed login attempts or unusual access patterns to NoticeStore.php
Network Indicators:
- HTTP POST requests to /src/store/NoticeStore.php containing SQL injection patterns in parameters
- Unusual database connection patterns from the web server
SIEM Query:
source="web_logs" AND uri="/src/store/NoticeStore.php" AND (param="noticeDesc" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|--|#|;)")
