CVE-2026-3133
📋 TL;DR
This SQL injection vulnerability in itsourcecode Document Management System 1.0 allows attackers to manipulate database queries through the login page's username parameter. Remote attackers can potentially execute arbitrary SQL commands, compromising the system. All deployments of version 1.0 with the vulnerable component are affected.
💻 Affected Systems
- itsourcecode Document Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive documents, user credential theft, and database manipulation leading to data integrity issues.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or failed login attempts.
🎯 Exploit Status
Exploit details are publicly available on GitHub. SQL injection via username parameter requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameterized queries or input sanitization to /loging.php to prevent SQL injection
Modify /loging.php to use prepared statements with parameterized queries instead of direct string concatenation
Web Application Firewall
allDeploy WAF rules to block SQL injection patterns in login requests
Add WAF rule: Detect and block SQL keywords (UNION, SELECT, INSERT, etc.) in username parameter
🧯 If You Can't Patch
- Isolate the Document Management System behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server only
🔍 How to Verify
Check if Vulnerable:
Test /loging.php with SQL injection payloads in username parameter (e.g., admin' OR '1'='1)Check Version:
Check system documentation or admin panel for version informationVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or produce no database errors📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL-like patterns in username field
Network Indicators:
- HTTP POST requests to /loging.php containing SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri_path="/loging.php" AND (username="*UNION*" OR username="*SELECT*" OR username="*' OR '*"*)
