1. Introduction
IBM InfoSphere Data Replication Dashboard uses default credentials for its web application. This means anyone knowing these credentials can log in and gain administrative access to the system. This affects confidentiality, integrity, and availability of data replicated through the dashboard. Systems running IBM InfoSphere Data Replication Dashboard with default settings are usually affected.
2. Technical Explanation
The vulnerability exists because the ‘dashboarduser’ account is created with a weak default password (‘dashboarduser’). An attacker can directly access the application using these credentials to gain full administrative control. There is no CVE currently associated with this specific issue, but it falls under CWE-798: Use of Hardcoded Credentials. A remote attacker could simply enter ‘dashboarduser’ as both username and password on the login page to compromise the system. Affected versions include those shipped with default configurations.
- Root cause: The application ships with a hardcoded, weak default credential for the dashboarduser account.
- Exploit mechanism: An attacker attempts to log in using the default username and password (‘dashboarduser’ / ‘dashboarduser’). Successful login grants administrative access.
- Scope: IBM InfoSphere Data Replication Dashboard versions running with default credentials are affected.
3. Detection and Assessment
You can confirm vulnerability by attempting to log in using the default credentials. A quick check is to try logging into the dashboard with ‘dashboarduser’ as both username and password. Scanning tools may not directly detect this without specific configuration. Check application logs for successful logins from the default account.
- Quick checks: Attempt login via web browser using username ‘dashboarduser’ and password ‘dashboarduser’.
- Scanning: Nessus plugin ID 16879 may identify this issue, but requires configuration.
- Logs and evidence: Check application logs for successful logins from the ‘dashboarduser’ account. The exact log location varies by installation, but look for authentication events related to the dashboard user.
# No command available as this is a web application check. Attempt login via browser.4. Solution / Remediation Steps
Secure the ‘dashboarduser’ account with a strong password. This will prevent unauthorized access to the dashboard and underlying data replication processes.
4.1 Preparation
- There are no dependencies, but ensure you have access to modify the dashboard user’s credentials. Change windows may be needed depending on internal policies.
4.2 Implementation
- Step 1: Log in to the IBM InfoSphere Data Replication Dashboard as ‘dashboarduser’ using the default password.
- Step 2: Navigate to the user management section (typically under Administration or Security settings).
- Step 3: Change the password for the ‘dashboarduser’ account to a strong, unique password. Ensure it meets complexity requirements if any are configured.
- Step 4: Log out and verify you can no longer log in with the default credentials.
4.3 Config or Code Example
Before
# Default configuration - no password change required for dashboarduser account.After
# Password changed for dashboarduser account to a strong, unique value. (Example: P@$$wOrd123)4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this issue. Least privilege limits the impact of compromised accounts. Safe defaults ensure systems are not shipped with easily guessable credentials. Regular password changes reduce exposure time if a password is leaked.
- Practice 1: Implement least privilege to restrict access only to authorized users and services.
- Practice 2: Enforce strong, unique passwords for all accounts.
4.5 Automation (Optional)
Automation is not generally suitable for this specific task due to the need for manual password changes within the application UI.
# No automation script available as this requires interaction with the web application UI.5. Verification / Validation
- Post-fix check: Attempt to log in using username ‘dashboarduser’ and password ‘dashboarduser’. Expected output: Authentication failure.
- Re-test: Repeat the quick checks from section 3; login should now fail with default credentials.
# Attempt login via browser using username ‘dashboarduser’ and password ‘dashboarduser’. Expect "Invalid Credentials" message.6. Preventive Measures and Monitoring
- Baselines: Update your security baseline to require strong, unique passwords for all accounts, including those created by default.
- Pipelines: Add a check during deployment to confirm that the ‘dashboarduser’ account has been changed from its default password.
7. Risks, Side Effects, and Roll Back
Changing the password could temporarily disrupt access if the new password is forgotten or lost. Ensure you document the new password securely. If issues occur, roll back by resetting the password to a known value (preferably a temporary strong password) and investigate further.
- Risk or side effect 1: Loss of access if the new password is forgotten. Mitigation: Document the new password securely and have a recovery process in place.
- Roll back: Log in with an administrator account (if available) and reset the ‘dashboarduser’ password to a known value. If no admin account exists, contact IBM support for assistance.
