⚠️ Risk & Real-World Impact
Worst Case
Attackers could access sensitive administrative interfaces, confidential documents, or user data that should be restricted, potentially leading to data breaches or privilege escalation.
Likely Case
Authenticated users accessing content they shouldn't have permission to view, such as other users' files or restricted administrative pages.
If Mitigated
Minimal impact if proper network segmentation, strong authentication, and additional access controls are implemented beyond the vulnerable application layer.
🎯 Exploit Status
Exploitation requires valid user credentials but involves simple direct URL requests to bypass authorization checks.

🔍 How to Verify
Check if Vulnerable:
Check iroha Board version via admin interface or configuration files. If version is v0.10.12 or earlier, system is vulnerable.
Check Version:
Check iroha Board configuration files or admin dashboard for version information
Verify Fix Applied:
After patching, attempt to access restricted content via direct URL requests while authenticated as non-privileged user. Access should be denied.
📡 Detection & Monitoring
Log Indicators:
- Multiple 200/302 responses to direct URL requests for restricted paths
- Access patterns showing users accessing content outside their normal role patterns
Network Indicators:
- HTTP requests to known restricted paths without preceding navigation
- Direct API calls to administrative endpoints from non-admin users
SIEM Query:
source="iroha_board" AND (url_path CONTAINS "/admin/" OR url_path CONTAINS "/restricted/") AND user_role!="admin" AND response_code=200
