CVE-2024-25270
📋 TL;DR
This CVE describes an Insecure Direct Object Reference (IDOR) vulnerability in Mirapolis LMS that allows authenticated users to manipulate ID and STEP parameters to access sensitive user data they shouldn't have permission to view. The vulnerability affects Mirapolis LMS version 4.6.XX and requires authenticated access to exploit.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could enumerate and exfiltrate all user data including personal information, credentials, and sensitive organizational data stored in the LMS.
Likely Case
Authenticated users accessing other users' profiles, course data, and potentially sensitive organizational information they shouldn't have access to.
If Mitigated
Limited data exposure if proper access controls and parameter validation are implemented.
🎯 Exploit Status
Exploit involves simple parameter manipulation (ID and STEP parameters). Public GitHub repository contains proof-of-concept.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
Check with Mirapolis vendor for security updates. Implement proper access controls and parameter validation in the application code.
🔧 Temporary Workarounds
Implement Access Control Validation
allAdd server-side validation to ensure users can only access objects they're authorized to view
Web Application Firewall Rules
allConfigure WAF to detect and block parameter manipulation attempts
🧯 If You Can't Patch
- Implement strict access controls and audit all user permissions
- Monitor application logs for unusual parameter manipulation patterns
🔍 How to Verify
Check if Vulnerable:
Test authenticated access to user objects by manipulating ID and STEP parameters to see if unauthorized data is returnedCheck Version:
Check Mirapolis LMS version in administration panel or configuration filesVerify Fix Applied:
Verify that parameter manipulation no longer returns unauthorized data and proper access controls are enforced📡 Detection & Monitoring
Log Indicators:
- Unusual parameter values in requests, especially sequential ID/STEP manipulation
- Multiple failed access attempts to different user IDs from same account
Network Indicators:
- Patterns of sequential parameter requests
- Unusual data access patterns from authenticated users
SIEM Query:
