🔧 Temporary Workarounds
Disable vulnerable endpoint
allTemporarily disable or restrict access to Activated_gridmap_model.php
# Add to .htaccess for Apache:
<Files "Activated_gridmap_model.php">
Order deny,allow
Deny from all
</Files>
# For nginx:
location ~ /Activated_gridmap_model\.php$ {

🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all user inputs
- Restrict database user permissions to minimum required privileges
🔍 How to Verify
Check if Vulnerable:
Check if Wavelog version is 1.8.5 and if Activated_gridmap_model.php exists without the security fix from commit 0bf2675d93602b591850790c8fcfced886eca423.Check Version:
Check Wavelog version in application configuration or admin panelVerify Fix Applied:
Verify that the Activated_gridmap_model.php file includes proper input sanitization and parameterized queries as shown in the fix commit.📡 Detection & Monitoring
