CVE-2024-31547
📋 TL;DR
CVE-2024-31547 is a critical SQL injection vulnerability in Computer Laboratory Management System v1.0 that allows attackers to execute arbitrary SQL commands via the 'id' parameter in the /admin/item/view_item.php endpoint. This affects all deployments of this specific software version. Attackers can potentially access, modify, or delete database contents.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access, privilege escalation, and potential system takeover through database manipulation.
If Mitigated
Limited impact if proper input validation and WAF rules are in place, though the vulnerability remains present.
🎯 Exploit Status
Public proof-of-concept exists showing SQL injection via the 'id' parameter. Exploitation requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the 'id' parameter before processing
Modify /admin/item/view_item.php to validate 'id' parameter as integer: if(!is_numeric($_GET['id'])) { die('Invalid input'); }
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:id "@rx (?i)(union|select|insert|update|delete|drop|create|alter|exec|xp_)" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
🧯 If You Can't Patch
- Isolate the system behind strict network segmentation and limit access to trusted IPs only
- Implement database user privilege reduction and enable detailed SQL query logging
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payload: /admin/item/view_item.php?id=1' OR '1'='1Check Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Test with same payload after implementing fixes - should return error or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple rapid requests to /admin/item/view_item.php with varying id parameters
- Database logs showing unexpected queries from web application user
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, etc.) in URL parameters
- Unusual traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_server" AND url="/admin/item/view_item.php" AND (url="*UNION*" OR url="*SELECT*" OR url="*OR '1'='1*")
