CVE-2024-53357
📋 TL;DR
Multiple SQL injection vulnerabilities in EasyVirt DCScope and CO2Scope allow authenticated attackers with low privileges to manipulate user, group, and role management functions. Attackers can add admin users, modify permissions, delete accounts, and potentially gain full administrative control. Organizations running affected versions of these products are at risk.
💻 Affected Systems
- EasyVirt DCScope
- EasyVirt CO2Scope
📦 What is this software?
Co2scope by Easyvirt
Dcscope by Easyvirt
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the application with administrative privileges, allowing attackers to create backdoor accounts, modify all user permissions, delete legitimate users, and potentially pivot to other systems.
Likely Case
Attackers with low-privilege accounts escalate to administrative privileges, then modify or delete legitimate user accounts while maintaining persistent access through created admin accounts.
If Mitigated
With proper input validation and parameterized queries, the SQL injection would be prevented, limiting attackers to their legitimate low-privilege access only.
🎯 Exploit Status
Exploitation requires authenticated access but only low privileges. SQL injection techniques are well-documented and tools like sqlmap could automate exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: DCScope > 8.6.0, CO2Scope > 1.3.0
Vendor Advisory: https://github.com/Elymaro/CVE/blob/main/EasyVirt/CVE-2024-53357.md
Restart Required: No
Instructions:
1. Check current version using the application's version command. 2. Contact EasyVirt vendor for patched versions. 3. Apply updates to DCScope > 8.6.0 and CO2Scope > 1.3.0. 4. Verify fixes by testing the vulnerable endpoints.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests to the vulnerable API endpoints.
Network Segmentation
allRestrict access to the vulnerable API endpoints (/api/user/* routes) to only trusted administrative networks.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all user management API endpoints
- Monitor and alert on suspicious API calls to user management endpoints, especially from low-privilege accounts
🔍 How to Verify
Check if Vulnerable:
Check application version: DCScope <= 8.6.0 or CO2Scope <= 1.3.0. Test API endpoints with SQL injection payloads (use caution in production).Check Version:
Check application documentation for version command, typically via web interface or configuration files.Verify Fix Applied:
After patching, attempt SQL injection tests on the vulnerable endpoints. Verify version is > 8.6.0 for DCScope or > 1.3.0 for CO2Scope.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts followed by successful authentication and API calls to user management endpoints
- User account creation/modification from non-admin accounts
Network Indicators:
- HTTP POST requests to /api/user/* endpoints containing SQL keywords (UNION, SELECT, INSERT, DELETE, etc.)
- Unusual patterns of API calls to user management functions
SIEM Query:
source="application_logs" AND ("SQL syntax" OR "SQL error" OR "database error") AND uri_path="/api/user/*"
