📋 TL;DR
This CSRF vulnerability in idccms v1.35 allows attackers to trick authenticated administrators into performing unauthorized database backup operations.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could force database backups to attacker-controlled locations, potentially exfiltrating sensitive data including user credentials, personal information, and application data.
Likely Case
Attackers create malicious web pages that trigger unauthorized database backups when visited by authenticated administrators, potentially leading to data exposure.
If Mitigated
With proper CSRF protections and network segmentation, impact is limited to unauthorized backup operations that administrators can detect and reverse.
🎯 Exploit Status
Exploitation requires the victim to be authenticated as an administrator and visit a malicious page while logged in. The exploit is simple to implement.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement CSRF tokens in /admin/dbBakMySQL_deal.php and validate all POST requests. Update to a newer version if available.
🔧 Temporary Workarounds
Implement CSRF Protection
allAdd CSRF tokens to the database backup form and validate them server-side
Edit /admin/dbBakMySQL_deal.php to include CSRF token generation and validation
Restrict Admin Access
allLimit administrative interface access to specific IP addresses or networks
Add IP-based restrictions to .htaccess or web server configuration for /admin/ directory
🧯 If You Can't Patch
- Implement network segmentation to isolate the CMS admin interface from untrusted networks
- Use browser extensions that block CSRF attacks and educate administrators about phishing risks
🔍 How to Verify
Check if Vulnerable:
Check if /admin/dbBakMySQL_deal.php?mudi=backup accepts POST requests without CSRF token validationCheck Version:
Check CMS version in admin panel or configuration filesVerify Fix Applied:
Test that database backup requests require valid CSRF tokens and fail without them📡 Detection & Monitoring
Log Indicators:
- Multiple database backup requests from unusual IP addresses
- Backup requests without corresponding admin login events
Network Indicators:
- HTTP POST requests to /admin/dbBakMySQL_deal.php with backup parameters from non-admin sources
SIEM Query:
source_ip NOT IN admin_ips AND uri_path='/admin/dbBakMySQL_deal.php' AND method='POST'
