⚠️ Risk & Real-World Impact
Worst Case
Administrators from one organization could gain unauthorized administrative access to other organizations' data, modify application configurations, or potentially escalate privileges across the entire Casdoor instance.
Likely Case
Unauthorized access to other organizations' settings and application configurations, potentially leading to data exposure or service disruption within affected organizations.
If Mitigated
Limited impact if proper network segmentation and access controls are in place, though cross-organization data exposure remains possible.
🎯 Exploit Status
Exploitation requires authenticated administrator access to any organization. The vulnerability involves simple URL manipulation techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v2.63.0
Vendor Advisory: https://github.com/casdoor/casdoor/releases/tag/v2.63.0
Restart Required: Yes
Instructions:
1. Backup current Casdoor configuration and data. 2. Download and install Casdoor v2.63.0 or later from the official releases. 3. Restart the Casdoor service. 4. Verify the fix by testing permission verification.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Casdoor instances per organization to prevent cross-organization access.
Access Control Lists
allImplement network-level ACLs to restrict administrative access to trusted IP addresses only.
🧯 If You Can't Patch
- Implement strict network segmentation between different organizations' administrative interfaces.
- Deploy a web application firewall (WAF) with URL manipulation detection rules.
🔍 How to Verify
Check if Vulnerable:
Test if authenticated administrators from one organization can access organization/application editing interfaces of other organizations by manipulating URLs.Check Version:
Check the Casdoor version in the web interface or via API endpoint /api/get-versionVerify Fix Applied:
After patching, verify that URL manipulation attempts to access other organizations' interfaces are properly blocked with permission errors.📡 Detection & Monitoring
