CVE-2025-4058
📋 TL;DR
CVE-2025-4058 is a critical SQL injection vulnerability in Projectworlds Online Examination System 1.0 that allows remote attackers to execute arbitrary SQL commands via the Pat_BloodGroup1 parameter in Bloodgroop_process.php. This affects all deployments of version 1.0, potentially compromising the entire database and application. Organizations using this software for online examinations are at risk of data theft, manipulation, or complete system takeover.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive examination data, student records, and administrative credentials, potentially leading to data exfiltration or system disruption.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing successful exploitation.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub, making this easily weaponizable. The SQL injection appears straightforward with minimal technical barriers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries and input validation.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to sanitize the Pat_BloodGroup1 parameter before processing
# Add to Bloodgroop_process.php before SQL execution:
$bloodGroup = filter_var($_POST['Pat_BloodGroup1'], FILTER_SANITIZE_STRING);
# Then use parameterized queries with prepared statements
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting Bloodgroop_process.php
# Example ModSecurity rule:
SecRule ARGS:Pat_BloodGroup1 "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering and rate limiting
- Implement network segmentation to restrict database access from the web application server
🔍 How to Verify
Check if Vulnerable:
Test the Bloodgroop_process.php endpoint with SQL injection payloads in the Pat_BloodGroup1 parameter and observe database errors or unexpected behaviorCheck Version:
Check system documentation or admin panel for version information, or examine PHP files for version headersVerify Fix Applied:
Attempt SQL injection after implementing fixes; successful protection should return proper error handling without database errors📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application
- Multiple failed login attempts following SQL errors
Network Indicators:
- HTTP POST requests to Bloodgroop_process.php with SQL keywords in parameters
- Unusual outbound database connections from web server
SIEM Query:
source="web_server.log" AND ("Bloodgroop_process.php" AND ("union" OR "select" OR "sleep" OR "benchmark"))
