CVE-2025-0172
📋 TL;DR
CVE-2025-0172 is a critical SQL injection vulnerability in code-projects Chat System 1.0 that allows remote attackers to execute arbitrary SQL commands via the 'id' parameter in the /admin/deleteroom.php file. This affects all installations of Chat System 1.0 with the vulnerable file accessible, potentially leading to database compromise, data theft, or system takeover.

📦 What is this software?
Chat System by Code Projects
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation to administrative access, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to chat system data, manipulation of user accounts and chat rooms, and potential extraction of sensitive information from the database.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, with database permissions restricted to prevent data manipulation.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Implement input validation and parameterized queries in /admin/deleteroom.php. Replace raw SQL queries with prepared statements using PDO or mysqli.
🔧 Temporary Workarounds
Input Validation Workaround
allAdd input validation to ensure 'id' parameter contains only numeric values
Edit /admin/deleteroom.php and add: if(!is_numeric($_GET['id'])) { die('Invalid input'); }
WAF Rule Implementation
linuxImplement web application firewall rules to block SQL injection patterns
For ModSecurity: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Block access to /admin/deleteroom.php at the web server level using .htaccess or nginx configuration
- Implement network segmentation to isolate the chat system from sensitive databases and systems
🔍 How to Verify
Check if Vulnerable:
Test the /admin/deleteroom.php endpoint with SQL injection payloads like: /admin/deleteroom.php?id=1' OR '1'='1Check Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Test with the same payloads and verify they are rejected or properly sanitized without executing SQL commands📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to /admin/deleteroom.php with SQL-like patterns in parameters
- Database connection errors or unusual query patterns
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in URL parameters
- Unusual traffic patterns to the /admin/ directory
SIEM Query:
source="web_server.logs" AND (url="/admin/deleteroom.php" AND (param="id" AND value MATCHES "[';]|OR|UNION|SELECT"))
