CVE-2025-45542
📋 TL;DR
A SQL injection vulnerability exists in the registrationform endpoint of CloudClassroom-PHP-Project v1.0, specifically in the pass parameter. Attackers can inject malicious SQL queries due to improper input validation, potentially compromising the database. This affects all deployments using the vulnerable version of this educational platform software.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution via database functions.
Likely Case
Unauthorized access to user data, credential theft, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing successful injection.
🎯 Exploit Status
Time-based blind SQL injection technique described in public disclosure. Exploitation requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement workarounds or manually fix vulnerable code by implementing parameterized queries and input validation.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation and sanitization for the pass parameter before processing
Edit registrationform.php to add: $pass = mysqli_real_escape_string($conn, $_POST['pass']);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Configure WAF to block SQL injection patterns in POST parameters
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with SQL injection filtering
- Implement network segmentation and restrict database access from application servers
🔍 How to Verify
Check if Vulnerable:
Test registrationform endpoint with SQL injection payloads in pass parameter and observe time delays or error responsesCheck Version:
Check project version in README or configuration filesVerify Fix Applied:
Attempt SQL injection after implementing fixes and verify no database interaction occurs📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed registration attempts with special characters
Network Indicators:
- POST requests to registrationform with SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="/registrationform" AND (param="pass" AND value MATCHES "(?i)(union|select|sleep|benchmark|' OR ')")
