CVE-2025-26702
📋 TL;DR
An improper input validation vulnerability in ZTE GoldenDB allows attackers to manipulate input data, potentially leading to unauthorized data modification or system disruption. This affects GoldenDB versions 6.1.03 through 6.1.03.04. Organizations running these specific versions of ZTE's GoldenDB database software are at risk.
💻 Affected Systems
- ZTE GoldenDB
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could manipulate database operations to corrupt data integrity, cause service disruption, or execute unauthorized commands through data manipulation.
Likely Case
Limited data manipulation leading to inconsistent database states or partial service degradation.
If Mitigated
With proper input validation controls and network segmentation, impact is limited to isolated database operations.
🎯 Exploit Status
Exploitation requires understanding of GoldenDB's input processing and likely requires some level of access to the database interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 6.1.03.04
Vendor Advisory: https://support.zte.com.cn/zte-iccp-isupport-webui/bulletin/detail/1820079027271819342
Restart Required: Yes
Instructions:
1. Download the latest GoldenDB version from ZTE support portal. 2. Backup current database and configuration. 3. Apply the update following ZTE's upgrade documentation. 4. Restart GoldenDB services. 5. Verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to GoldenDB to only trusted systems and applications.
iptables -A INPUT -p tcp --dport [GoldenDB_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [GoldenDB_port] -j DROP
Input Validation Enhancement
allImplement additional input validation at application layer before passing data to GoldenDB.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate GoldenDB from untrusted networks
- Deploy additional monitoring and alerting for unusual database operations
🔍 How to Verify
Check if Vulnerable:
Check GoldenDB version using the database management interface or configuration files. If version is between 6.1.03 and 6.1.03.04 inclusive, system is vulnerable.Check Version:
Check GoldenDB configuration files or use database management tools to query version information.Verify Fix Applied:
Verify GoldenDB version is greater than 6.1.03.04 and test database operations with various input scenarios.📡 Detection & Monitoring
Log Indicators:
- Unusual input patterns in database logs
- Unexpected data manipulation operations
- Error messages related to input validation
Network Indicators:
- Unusual database query patterns from unexpected sources
- Multiple failed input validation attempts
