CVE-2024-48249
📋 TL;DR
Wavelog 1.8.5 contains an unauthenticated SQL injection vulnerability in Gridmap_model.php that allows attackers to execute arbitrary SQL commands via band, sat, propagation, or mode parameters. This affects all Wavelog installations running version 1.8.5. Attackers can potentially access, modify, or delete database content without authentication.
💻 Affected Systems
- Wavelog
📦 What is this software?
Wavelog by Wavelog
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or remote code execution via database functions
Likely Case
Database information disclosure, data manipulation, or denial of service
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented
🎯 Exploit Status
Exploitation requires no authentication and uses simple SQL injection techniques
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in commit 0bf2675d93602b591850790c8fcfced886eca423
Vendor Advisory: https://github.com/wavelog/wavelog/commit/0bf2675d93602b591850790c8fcfced886eca423
Restart Required: No
Instructions:
1. Update to latest Wavelog version 2. Apply commit 0bf2675d93602b591850790c8fcfced886eca423 3. Replace Gridmap_model.php with patched version
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for band, sat, propagation, and mode parameters
# Add input validation in Gridmap_model.php
# Example: if(!preg_match('/^[a-zA-Z0-9]+$/', $input)) { return false; }
Web Application Firewall
allDeploy WAF with SQL injection protection rules
# Configure WAF to block SQL injection patterns
# Example mod_security rules: SecRule ARGS "@detectSQLi" "id:1000,phase:2,deny"
🧯 If You Can't Patch
- Disable or restrict access to Gridmap_model.php functionality
- Implement network segmentation and restrict database access from web server
🔍 How to Verify
Check if Vulnerable:
Test Gridmap_model.php endpoints with SQL injection payloads in band, sat, propagation, or mode parametersCheck Version:
Check Wavelog version in admin panel or config filesVerify Fix Applied:
Verify Gridmap_model.php uses parameterized queries and proper input validation📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed parameter validation attempts
- Suspicious parameter values in web server logs
Network Indicators:
- SQL injection patterns in HTTP requests
- Unusual database connection patterns
SIEM Query:
