How the CVE Works:
CVE-2025-26704 is an Improper Privilege Management vulnerability in ZTE GoldenDB versions 6.1.03 through 6.1.03.05. This flaw allows attackers to escalate privileges by exploiting improper access control mechanisms within the database system. The vulnerability arises due to insufficient validation of user permissions, enabling unauthorized users to execute administrative commands or access restricted data. Attackers can leverage this to gain full control over the database, potentially leading to data breaches, unauthorized modifications, or service disruptions. The CVSS 4.0 severity score indicates a critical risk due to the high impact on confidentiality, integrity, and availability.
DailyCVE Form:
Platform: ZTE GoldenDB
Version: 6.1.03 – 6.1.03.05
Vulnerability: Privilege Escalation
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
import requests
target_url = "http://target-db-server/admin"
payload = {"command": "escalate_privileges", "user": "attacker"}
response = requests.post(target_url, data=payload)
if response.status_code == 200:
print("Privilege Escalation Successful!")
2. Manual Exploit Steps:
- Identify the target ZTE GoldenDB version.
- Craft a malicious request to the administrative endpoint.
- Exploit the improper privilege validation to escalate privileges.
Protection:
1. Patch Application:
- Apply the latest security patch provided by ZTE for GoldenDB versions 6.1.03.06 and above.
2. Access Control Hardening:
- Implement strict role-based access control (RBAC) policies.
- Regularly audit user permissions and privileges.
3. Network Security:
- Restrict access to administrative interfaces using firewalls.
- Use VPNs for remote database access.
4. Monitoring and Logging:
- Enable detailed logging of all administrative actions.
- Use SIEM tools to detect unusual privilege escalation attempts.
5. Code Example for Logging:
import logging
logging.basicConfig(filename='db_audit.log', level=logging.INFO)
logging.info(f"User {user} attempted privilege escalation at {timestamp}")
6. Mitigation Commands:
- Update database:
sudo apt-get update && sudo apt-get upgrade golden-db
- Restrict admin access:
iptables -A INPUT -p tcp --dport 8080 -s trusted-ip -j ACCEPT iptables -A INPUT -p tcp --dport 8080 -j DROP
7. Vulnerability Scanning:
- Use tools like Nessus or OpenVAS to scan for vulnerable GoldenDB instances.
8. Incident Response:
- Isolate compromised systems immediately.
- Conduct a forensic analysis to identify the root cause.
By following these steps, organizations can mitigate the risks associated with CVE-2025-26704 and protect their ZTE GoldenDB systems from privilege escalation attacks.
