CVE-2026-25202

9.8 CRITICAL
Authentication Bypass

📋 TL;DR

MagicINFO 9 Server versions below 21.1090.1 contain hardcoded database credentials, allowing attackers to authenticate and manipulate the database. This affects all deployments of the vulnerable software versions. The hardcoded credentials provide unauthorized database access.

💻 Affected Systems

Products:
  • MagicINFO 9 Server
Versions: All versions less than 21.1090.1
Operating Systems: Windows Server (typical deployment)
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations are vulnerable. No special configuration required for exploitation.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, data destruction, or full system takeover via database manipulation.

🟠

Likely Case

Unauthorized database access allowing data extraction, modification, or deletion of sensitive information.

🟢

If Mitigated

Limited impact if network segmentation prevents external access and internal controls detect unauthorized database activity.

🌐 Internet-Facing: HIGH - Internet-facing instances are directly exploitable without authentication.
🏢 Internal Only: HIGH - Internal instances remain vulnerable to insider threats or lateral movement.

🎯 Exploit Status

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

Exploitation requires only knowledge of the hardcoded credentials and database connection method.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 21.1090.1 or later

Vendor Advisory: https://security.samsungtv.com/securityUpdates

Restart Required: Yes

Instructions:

1. Download MagicINFO 9 Server version 21.1090.1 or later from Samsung. 2. Backup current configuration and data. 3. Install the update following vendor instructions. 4. Restart the server. 5. Verify database credentials are no longer hardcoded.

🔧 Temporary Workarounds

Network Isolation

all

Restrict database port access to only trusted IP addresses

Windows Firewall: New-NetFirewallRule -DisplayName "Block MagicINFO DB" -Direction Inbound -LocalPort 1433 -Protocol TCP -Action Block
Linux iptables: iptables -A INPUT -p tcp --dport 1433 -j DROP

Database Credential Rotation

windows

Change database credentials and update application configuration

SQL Server: ALTER LOGIN [magicinfo_user] WITH PASSWORD = 'NewStrongPassword123!'
Update MagicINFO configuration file with new credentials

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate MagicINFO server from untrusted networks
  • Deploy database activity monitoring to detect unauthorized access attempts

🔍 How to Verify

Check if Vulnerable:

Check MagicINFO Server version in administration panel or installation directory. Versions below 21.1090.1 are vulnerable.

Check Version:

Check MagicINFO Server administration interface or installation directory for version information

Verify Fix Applied:

Verify version is 21.1090.1 or higher and attempt to authenticate with previously known hardcoded credentials (should fail).

📡 Detection & Monitoring

Log Indicators:

  • Failed authentication attempts with hardcoded credentials
  • Unusual database queries from MagicINFO application account
  • Database connection attempts from unexpected IP addresses

Network Indicators:

  • Database port (typically 1433) connections from unauthorized sources
  • SQL protocol traffic to MagicINFO server from external networks

SIEM Query:

source="magicinfo_logs" AND (event_type="authentication_failure" OR db_query="*sensitive_table*")
