CVE-2017-17616
📋 TL;DR
Event Search Script 1.0 contains a SQL injection vulnerability in the city parameter of the /event-list endpoint. This allows attackers to execute arbitrary SQL commands on the database. Anyone running Event Search Script 1.0 is affected.
💻 Affected Systems
- Event Search Script
📦 What is this software?
Event Calendar Category Script by Event Calendar Category Script Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, and potential remote code execution via database functions.
Likely Case
Database information disclosure, authentication bypass, and data manipulation.
If Mitigated
Limited impact with proper input validation and parameterized queries in place.
🎯 Exploit Status
Multiple public exploit scripts available, trivial to exploit with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: N/A
Restart Required: No
Instructions:
No official patch available. Replace with secure alternative or implement custom fixes.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize city parameter input
Implement parameterized queries or prepared statements in PHP code
WAF Rule
allBlock SQL injection patterns in the city parameter
Add WAF rule: Detect and block SQL keywords in /event-list requests
🧯 If You Can't Patch
- Block access to /event-list endpoint at network perimeter
- Implement strict input validation and output encoding in application layer
🔍 How to Verify
Check if Vulnerable:
Test /event-list endpoint with SQL injection payloads in city parameter (e.g., city=' OR '1'='1)Check Version:
Check script version in source code or documentation filesVerify Fix Applied:
Verify SQL injection payloads no longer execute and return expected error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests with SQL keywords to /event-list
Network Indicators:
- HTTP requests to /event-list with SQL injection patterns in parameters
SIEM Query:
source="web_logs" AND uri_path="/event-list" AND (param="city" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|--|#|;)")
