CVE-2025-25513

9.8 CRITICAL

📋 TL;DR

Seacms versions up to 13.3 contain a SQL injection vulnerability in admin_members.php that allows attackers to execute arbitrary SQL commands. This affects all Seacms installations running vulnerable versions, potentially compromising the entire database and system. Attackers can exploit this to steal sensitive data, modify content, or gain administrative access.

💻 Affected Systems

Products:
  • Seacms
Versions: <= 13.3
Operating Systems: All operating systems running PHP
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all installations using the vulnerable admin_members.php file. Requires PHP environment with database connectivity.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, privilege escalation to admin, remote code execution, and full system takeover.

🟠

Likely Case

Database extraction of sensitive information (user credentials, admin accounts, content), unauthorized content modification, and potential backdoor installation.

🟢

If Mitigated

Limited impact with proper input validation, parameterized queries, and WAF protection blocking malicious SQL payloads.

🌐 Internet-Facing: HIGH - Web applications are directly accessible from the internet, making them prime targets for automated scanning and exploitation.
🏢 Internal Only: MEDIUM - Internal systems are less exposed but still vulnerable to insider threats or compromised internal hosts.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires admin access to the admin_members.php endpoint. Public proof-of-concept exists in GitHub repository.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: > 13.3

Vendor Advisory: Not available

Restart Required: No

Instructions:

1. Upgrade Seacms to version newer than 13.3. 2. Replace admin_members.php with patched version. 3. Verify database integrity. 4. Change all database and admin credentials.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation and parameterized queries for all user inputs in admin_members.php

Modify PHP code to use prepared statements: $stmt = $pdo->prepare('SELECT * FROM members WHERE id = ?'); $stmt->execute([$user_input]);

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns

Add WAF rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Restrict access to admin_members.php using IP whitelisting or authentication requirements
  • Implement database monitoring and alerting for unusual SQL queries

🔍 How to Verify

Check if Vulnerable:

Check if admin_members.php exists and contains unsanitized user input in SQL queries. Test with SQL injection payloads in controlled environment.

Check Version:

Check Seacms version in configuration files or admin panel: grep -r 'version' /path/to/seacms/ or check admin dashboard

Verify Fix Applied:

Verify admin_members.php uses parameterized queries and input validation. Test with SQL injection attempts that should be blocked.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts to admin panel
  • Unexpected file modifications to admin_members.php

Network Indicators:

  • HTTP requests to admin_members.php with SQL keywords in parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND (uri="*admin_members.php*" AND (param="*UNION*" OR param="*SELECT*" OR param="*INSERT*" OR param="*DELETE*"))
