CVE-2025-7950
📋 TL;DR
CVE-2025-7950 is a critical SQL injection vulnerability in code-projects Public Chat Room 1.0 that allows attackers to execute arbitrary SQL commands via the Username parameter in /login.php. This affects all deployments of Public Chat Room 1.0 with the vulnerable login.php file. Attackers can exploit this remotely without authentication.
💻 Affected Systems
- code-projects Public Chat Room
📦 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 if database functions allow it.
Likely Case
Database information disclosure, authentication bypass, and potential privilege escalation leading to unauthorized access to chat room data.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub and vuldb. SQL injection via Username parameter is straightforward to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd input validation to /login.php to sanitize Username parameter and prevent SQL injection.
Edit /login.php to implement parameterized queries or proper input escaping
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in login requests.
Configure WAF to detect and block SQL injection patterns in POST parameters
🧯 If You Can't Patch
- Isolate the chat room application in a segmented network to limit potential damage
- Implement strict network access controls and monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test /login.php with SQL injection payloads in Username parameter (e.g., ' OR '1'='1). Check if application returns database errors or unexpected behavior.Check Version:
Check the application version in source code or configuration files, typically in readme or version files.Verify Fix Applied:
After implementing fixes, test with same SQL injection payloads to confirm they are blocked and no longer cause database errors.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from login.php
- Multiple failed login attempts with SQL patterns
Network Indicators:
- HTTP POST requests to /login.php containing SQL keywords (UNION, SELECT, etc.) in parameters
SIEM Query:
source="web_logs" AND uri="/login.php" AND (payload="*UNION*" OR payload="*SELECT*" OR payload="*OR '1'='1*")
