How the CVE Works:
CVE-2025-26703 is an Improper Privilege Management vulnerability in ZTE GoldenDB versions 6.1.03 through 6.1.03.04. This flaw allows attackers to escalate privileges by exploiting improper access controls 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 elevated privileges, potentially compromising the entire database system. The issue is classified as critical due to its potential impact on data integrity, confidentiality, and system availability.
DailyCVE Form:
Platform: ZTE GoldenDB
Version: 6.1.03 – 6.1.03.04
Vulnerability: Privilege Escalation
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
- Identify Target: Confirm the ZTE GoldenDB version is within the vulnerable range (6.1.03 – 6.1.03.04).
- Craft Payload: Use a crafted request to bypass privilege checks. Example:
curl -X POST -d "admin_command=privilege_escalation" http://target-db/api
- Execute Attack: Send the payload to the database API endpoint to gain elevated privileges.
Protection:
- Patch Installation: Apply the latest security patches provided by ZTE.
- Access Control: Implement strict role-based access control (RBAC) policies.
- Input Validation: Ensure all user inputs are validated to prevent privilege escalation attempts.
- Monitoring: Use intrusion detection systems (IDS) to monitor for unusual activity.
Analytics:
- CVSS Score: 9.8 (Critical)
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: Low
- User Interaction: None
- Scope: Unchanged
Commands:
- Check Version:
db_version=$(ssh user@target-db "goldendb --version") echo $db_version
- Apply Patch:
ssh user@target-db "sudo apt-get update && sudo apt-get install goldendb-patch"
- Monitor Logs:
tail -f /var/log/goldendb/access.log | grep "privilege_escalation"
Code Example (Input Validation):
def validate_user_input(command):
allowed_commands = [bash]
if command not in allowed_commands:
raise ValueError("Unauthorized command")
return True
