CVE-2024-22568
📋 TL;DR
FlyCms v1.0 contains a Cross-Site Request Forgery (CSRF) vulnerability in the score deletion endpoint (/system/score/del). This allows attackers to trick authenticated users into performing unintended actions, potentially deleting score data. All users running FlyCms v1.0 with the vulnerable endpoint accessible are affected.
💻 Affected Systems
- FlyCms
📦 What is this software?
Flycms by Flycms Project
⚠️ Risk & Real-World Impact
Worst Case
Attackers could delete all score data, causing data loss and disrupting application functionality for all users.
Likely Case
Targeted deletion of specific score entries, potentially affecting user reputation systems or scoring mechanisms.
If Mitigated
With proper CSRF protections, no unauthorized actions can be performed through forged requests.
🎯 Exploit Status
CSRF attacks are well-understood and easy to implement; exploitation requires the victim to be authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None provided
Restart Required: No
Instructions:
No official patch available. Implement CSRF protection tokens on all state-changing endpoints.
🔧 Temporary Workarounds
Implement CSRF Protection
allAdd CSRF tokens to all POST requests and validate them server-side
Modify /system/score/del endpoint to require and validate CSRF tokens
Disable Endpoint
allTemporarily disable the vulnerable endpoint until proper fix is implemented
Comment out or remove route for /system/score/del in routing configuration
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block CSRF attempts
- Restrict access to /system/score/del endpoint to specific IP ranges or users
🔍 How to Verify
Check if Vulnerable:
Test if /system/score/del endpoint accepts POST requests without CSRF token validationCheck Version:
Check FlyCms version in admin panel or configuration filesVerify Fix Applied:
Verify that CSRF tokens are required and validated for /system/score/del endpoint📡 Detection & Monitoring
Log Indicators:
- Multiple POST requests to /system/score/del from same IP with different session IDs
- Score deletion events without corresponding user actions in audit logs
Network Indicators:
- HTTP POST requests to /system/score/del without Referer header or with suspicious origins
SIEM Query:
source="web_logs" AND uri="/system/score/del" AND method="POST" AND (NOT csrf_token=*)
