CVE-2025-46179
📋 TL;DR
This SQL injection vulnerability in CloudClassroom-PHP v1.0 allows attackers to execute arbitrary SQL commands through the unsanitized squeryx parameter in askquery.php. This affects all deployments of CloudClassroom-PHP v1.0 that expose the vulnerable file, potentially leading to data theft, modification, or system compromise.
💻 Affected Systems
- CloudClassroom-PHP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, data destruction, privilege escalation to administrative access, and potential remote code execution via database functions.
Likely Case
Unauthorized access to sensitive student/teacher data, grade manipulation, user account takeover, and potential lateral movement within the database.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection, though other vulnerabilities may still exist.
🎯 Exploit Status
SQL injection is well-understood with many automated tools available. The vulnerability requires no authentication and has public proof-of-concept references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
1. Review the askquery.php file
2. Replace direct SQL concatenation with parameterized queries
3. Implement input validation for the squeryx parameter
4. Test the fix thoroughly before deployment
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests
Input Validation Filter
allAdd input validation to reject suspicious characters in squeryx parameter
// In askquery.php, add before SQL execution:
$squeryx = preg_replace('/[^a-zA-Z0-9\s]/', '', $_POST['squeryx']);
🧯 If You Can't Patch
- Block external access to askquery.php via firewall rules or web server configuration
- Implement database user with minimal privileges (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test the askquery.php endpoint with SQL injection payloads like: squeryx=test' OR '1'='1Check Version:
Check project documentation or version files; typically in README or config filesVerify Fix Applied:
Attempt SQL injection tests and verify they are rejected or properly handled without database errors📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in request logs
- Multiple failed login attempts via askquery.php
- Database error messages containing SQL fragments
Network Indicators:
- Unusual database connection patterns from web server
- Large data transfers from database to external IPs
SIEM Query:
source="web_logs" AND uri="*askquery.php*" AND (query="*' OR*" OR query="*;--*" OR query="*UNION*" OR query="*SELECT*FROM*")
