CVE-2025-25519
📋 TL;DR
SeaCMS versions up to 13.3 contain a SQL injection vulnerability in the admin_zyk.php file that allows attackers to execute arbitrary SQL commands. This affects all SeaCMS installations running vulnerable versions, potentially compromising the entire database and application. Attackers can exploit this to steal sensitive data, modify content, or gain administrative access.
💻 Affected Systems
- SeaCMS
📦 What is this software?
Seacms by Seacms
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation to admin, remote code execution via database functions, and full system takeover.
Likely Case
Unauthorized data extraction from the database, including user credentials, sensitive content, and configuration data, followed by administrative account takeover.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection, though other vulnerabilities might still exist.
🎯 Exploit Status
Exploitation requires admin access to the admin_zyk.php endpoint. The SQL injection is straightforward with publicly available proof-of-concept code.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: > 13.3
Vendor Advisory: https://github.com/Colorado-all/cve/blob/main/seacms/seacms%20V13.3-sql-8.md
Restart Required: No
Instructions:
1. Upgrade SeaCMS to version newer than 13.3. 2. If upgrade is not possible, apply the patch from the GitHub reference. 3. Replace admin_zyk.php with the patched version. 4. Clear any cached files.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for all user inputs in admin_zyk.php
File Restriction
linuxRestrict access to admin_zyk.php file using web server configuration or authentication
# Apache: <Files "admin_zyk.php"> Require all denied </Files>
# Nginx: location ~ admin_zyk\.php { deny all; }
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns targeting admin_zyk.php
- Restrict network access to the SeaCMS admin interface to trusted IP addresses only
🔍 How to Verify
Check if Vulnerable:
Check if admin_zyk.php exists in your SeaCMS installation and review the code for lack of parameterized queries or input validationCheck Version:
Check the SeaCMS version in the admin panel or look for version information in configuration filesVerify Fix Applied:
Test the admin_zyk.php endpoint with SQL injection payloads to confirm they are blocked, and verify the SeaCMS version is >13.3📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs from admin_zyk.php
- Multiple failed login attempts followed by admin_zyk.php access
- SQL error messages containing injection payloads
Network Indicators:
- HTTP POST requests to admin_zyk.php containing SQL keywords like UNION, SELECT, INSERT
- Unusual database connection patterns from the web server
SIEM Query:
source="web_logs" AND uri="*admin_zyk.php*" AND (query="*UNION*" OR query="*SELECT*" OR query="*INSERT*")
