How the CVE Works:
CVE-2025-26705 is an Improper Privilege Management vulnerability in ZTE GoldenDB, affecting versions 6.1.03 through 6.1.03.05. This flaw allows attackers to escalate privileges by exploiting insufficient validation of user permissions. When a low-privileged user sends a crafted request to the database, the system fails to properly verify the user’s access level, granting unauthorized privileges. This can lead to full control over the database, enabling data manipulation, extraction, or system compromise. The vulnerability stems from improper handling of role-based access control (RBAC) mechanisms, allowing attackers to bypass intended restrictions.
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:
- Crafting Malicious Requests: Attackers can use tools like `curl` or `Postman` to send crafted requests to the database API.
Example:
curl -X POST -d '{"user":"low_priv_user","action":"admin_action"}' http://target-db/api
2. Exploit Script: A Python script can automate privilege escalation by sending malicious payloads.
Example:
import requests
url = "http://target-db/api"
payload = {"user": "low_priv_user", "action": "admin_action"}
response = requests.post(url, json=payload)
print(response.text)
3. Metasploit Module: If a Metasploit module is developed, it can be used for exploitation.
Example:
use exploit/zte_goldendb_priv_esc set RHOSTS target-db run
Protection:
- Patch Application: Apply the latest security patches from ZTE to fix the vulnerability.
- Input Validation: Implement strict input validation to ensure only authorized actions are performed.
- Role-Based Access Control (RBAC): Enforce proper RBAC mechanisms to restrict user privileges.
- Network Segmentation: Isolate the database server to limit exposure to potential attackers.
- Log Monitoring: Monitor logs for unusual activity, such as repeated privilege escalation attempts.
Example:
tail -f /var/log/goldendb/access.log | grep "admin_action"
6. Firewall Rules: Restrict access to the database API using firewall rules.
Example:
iptables -A INPUT -p tcp --dport 8080 -s trusted_ip -j ACCEPT iptables -A INPUT -p tcp --dport 8080 -j DROP
7. Regular Audits: Conduct regular security audits to identify and mitigate vulnerabilities.
Analytics:
- CVSS Score: 9.8 (Critical)
