🔧 Temporary Workarounds
API Endpoint Restriction
allRestrict access to the vulnerable /module/Api/Diario endpoint using web server configuration or network controls.
# Apache example: <Location /module/Api/Diario> Deny from all </Location>
# Nginx example: location /module/Api/Diario { deny all; }
Enhanced Authentication
allImplement additional authentication layers or API gateway controls for all API endpoints.

- Implement strict network segmentation to isolate the i-Educar application from untrusted networks
- Deploy a Web Application Firewall (WAF) with rules to detect and block authorization bypass attempts
🔍 How to Verify
Check if Vulnerable:
Check if your i-Educar version is 2.9.0 or earlier and if the /module/Api/Diario endpoint is accessible.Check Version:
Check i-Educar configuration files or admin interface for version informationVerify Fix Applied:
Test if authorization controls are properly enforced on the /module/Api/Diario endpoint after implementing workarounds.📡 Detection & Monitoring
