How the CVE Works:
CVE-2025-26702 is a critical vulnerability in ZTE GoldenDB versions 6.1.03 through 6.1.03.04, caused by improper input validation. This flaw allows attackers to manipulate input data, potentially leading to unauthorized access, data corruption, or system crashes. The vulnerability arises when the database fails to properly sanitize or validate user-supplied input, enabling malicious actors to inject crafted data that exploits the system’s logic. This can result in arbitrary code execution, privilege escalation, or denial of service. The CVSS 4.0 score reflects its high severity due to the potential for widespread impact on affected systems.
DailyCVE Form:
Platform: ZTE GoldenDB
Version: 6.1.03 – 6.1.03.04
Vulnerability: Input Validation Bypass
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
import requests
target_url = "http://target-goldendb-server/api"
payload = {"input": "<malicious_data>"}
response = requests.post(target_url, json=payload)
if response.status_code == 200:
print("Exploit successful!")
else:
print("Exploit failed.")
2. Exploit Steps:
- Identify the vulnerable endpoint in ZTE GoldenDB.
- Craft malicious input data to bypass validation.
- Send the payload to the target system.
- Observe system behavior for signs of compromise.
Protection:
1. Patch Application:
- Apply the latest security patches from ZTE for GoldenDB versions 6.1.03.05 and above.
2. Input Validation:
- Implement strict input validation on all user-supplied data.
- Use regex or whitelisting to filter out malicious input.
3. Network Hardening:
- Restrict access to GoldenDB endpoints using firewalls.
- Use VPNs for secure remote access.
4. Monitoring:
- Deploy intrusion detection systems (IDS) to monitor for unusual activity.
- Regularly review logs for signs of exploitation attempts.
5. Code Fix Example:
def validate_input(user_input):
if not user_input.isalnum():
raise ValueError("Invalid input detected!")
return user_input
6. Commands for System Admins:
- Check current version: `goldendb –version`
– Update GoldenDB: `sudo apt-get update && sudo apt-get install goldendb`
– Restart service: `sudo systemctl restart goldendb`
7. Analytics:
- Monitor CVSS score changes for CVE-2025-26702.
- Track patch adoption rates across affected systems.
- Analyze attack patterns from threat intelligence feeds.
By following these steps, organizations can mitigate the risk posed by CVE-2025-26702 and ensure the security of their ZTE GoldenDB deployments.
