CVE-2025-7157
📋 TL;DR
CVE-2025-7157 is a critical SQL injection vulnerability in code-projects Online Note Sharing 1.0 that allows attackers to execute arbitrary SQL commands via the username/password parameters in /login.php. This affects all deployments of Online Note Sharing 1.0, potentially compromising the entire database. Attackers can exploit this remotely without authentication.
💻 Affected Systems
- code-projects Online Note Sharing
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential server takeover via SQL injection to RCE chain.
Likely Case
Database information disclosure, credential theft, and unauthorized access to user notes and sensitive data.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, though SQL injection attempts would still be logged.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub and vuldb.com. SQL injection in login pages is commonly weaponized due to high impact.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to a different note-sharing solution or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious payloads.
Input Validation Filter
allAdd input validation to sanitize username and password parameters before processing.
Add PHP code to validate and sanitize $_POST['username'] and $_POST['password'] using mysqli_real_escape_string() or prepared statements.
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads like ' OR '1'='1 in username/password fields and observe if authentication bypass occurs.Check Version:
Check the application version in configuration files or about pages. Look for 'Online Note Sharing 1.0' references.Verify Fix Applied:
Verify that parameterized queries are implemented in login.php and SQL injection payloads no longer bypass authentication.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL-like patterns
- Successful logins from unexpected IP addresses
Network Indicators:
- HTTP POST requests to /login.php containing SQL keywords like UNION, SELECT, OR, --
SIEM Query:
source="web_logs" AND uri_path="/login.php" AND (request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%" OR request_body LIKE "%OR%'1'='1%")
