Restart Required: No
Instructions:
No official patch available. Consider: 1. Replace with alternative software 2. Apply manual code fixes 3. Implement workarounds
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd input validation and parameterized queries to searchJob.php
Edit searchJob.php to use prepared statements with parameterized queries
Web Application Firewall (WAF)
allDeploy WAF with SQL injection protection rules
Configure WAF to block SQL injection patterns in request parameters
🧯 If You Can't Patch
- Block external access to searchJob.php via firewall rules or web server configuration

🔍 How to Verify
Check if Vulnerable:
Test searchJob.php with SQL injection payloads in jobType or jobFrequency parameters (e.g., ' OR '1'='1)Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with same SQL injection payloads after fixes - should return error or no database manipulation📡 Detection & Monitoring
