📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access, user account manipulation, and potential privilege escalation within the document management system.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
Exploit code is publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ 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 and Sanitization
allImplement proper input validation and parameterized queries for the user2del parameter in /deluser.php
Modify /deluser.php to use prepared statements: $stmt = $conn->prepare('DELETE FROM users WHERE id = ?'); $stmt->bind_param('i', $user2del); $stmt->execute();
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection attempts targeting /deluser.php
Add WAF rule: Block requests to /deluser.php containing SQL keywords in user2del parameter
🧯 If You Can't Patch
- Restrict access to /deluser.php using IP whitelisting or authentication requirements
- Disable or remove /deluser.php if user deletion functionality is not required
🔍 How to Verify
Check if Vulnerable:
Test /deluser.php with SQL injection payloads like: /deluser.php?user2del=1' OR '1'='1Check Version:
Check system documentation or admin panel for version informationVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or no database manipulation📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple DELETE requests to /deluser.php with suspicious parameters
- Database logs showing unexpected queries from web application
Network Indicators:
- HTTP requests to /deluser.php containing SQL keywords (UNION, SELECT, INSERT, etc.)
- Unusual traffic patterns to the document management system
SIEM Query:
source="web_logs" AND uri="/deluser.php" AND (user2del="*'*" OR user2del="*OR*" OR user2del="*UNION*" OR user2del="*SELECT*")
