1. Introduction
SolarWinds Log and Event Manager Default Credentials allows unauthenticated administrator access to a security information and event management (SIEM) solution. This is because the web server uses well-known default credentials for protection. Successful exploitation could allow attackers to fully compromise the SIEM, impacting confidentiality, integrity, and availability of logged data and connected systems.
2. Technical Explanation
The SolarWinds Log and Event Manager install is protected by a set of default administrator credentials that are not changed during initial setup. An attacker can use these credentials to gain full administrative control over the appliance via the web interface. There is no known CVE associated with this specific issue, but it represents a fundamental security misconfiguration. A simple example would be an attacker attempting to log in using the default username and password combination from an external network.
- Root cause: Use of weak or default credentials on a critical system interface.
- Exploit mechanism: An attacker attempts to authenticate with default credentials via the web application login page. If successful, they gain administrator access.
- Scope: SolarWinds Log and Event Manager installations are affected. Specific versions were not provided in the context.
3. Detection and Assessment
You can confirm if a system is vulnerable by checking the current user account for the ‘admin’ user, or scanning for open ports associated with the web server.
- Quick checks: Check the SolarWinds Log and Event Manager web interface login page to see if default credentials are still active.
- Scanning: Nessus vulnerability ID e583e3fd can be used as an example for detection, but is not exhaustive.
- Logs and evidence: Review system logs for failed login attempts with the ‘admin’ username. Specific log paths were not provided in the context.
4. Solution / Remediation Steps
Change the password for the ‘admin’ user account immediately. This is a critical step to secure your SIEM installation.
4.1 Preparation
- Dependencies: Access to the SolarWinds Log and Event Manager web interface with administrative privileges. A roll back plan involves restoring from the backup if issues occur.
- Change window needs: This change should be performed during a scheduled maintenance window with appropriate approval.
4.2 Implementation
- Step 1: Log in to the SolarWinds Log and Event Manager web interface as an administrator.
- Step 2: Navigate to System Settings > Account Settings.
- Step 3: Change the password for the ‘admin’ user account to a strong, unique password.
- Step 4: Confirm the new password.
- Step 5: Save the changes.
4.3 Config or Code Example
Before
Default 'admin' password in use.
After
Strong, unique password set for 'admin' user account.
4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this issue. Least privilege reduces impact if an account is compromised. Safe defaults ensure systems start in a secure state. A strong password policy enforces complex passwords.
- Practice 1: Implement least privilege principles, limiting access to only those users who require it.
- Practice 2: Enforce safe default configurations on all systems and applications.
4.5 Automation (Optional)
No suitable automation script is provided in the context.
5. Verification / Validation
- Post-fix check: Attempt to log in with the original default ‘admin’ credentials. The login should fail.
- Re-test: Re-run the detection method from Section 3, which should no longer identify the vulnerability.
- Monitoring: Monitor system logs for failed login attempts with the ‘admin’ username to detect any further attempts using default credentials.
Login attempt with default credentials should be rejected.
6. Preventive Measures and Monitoring
Update security baselines or policies to include a requirement for changing default passwords on all systems. Implement checks in CI/CD pipelines to prevent deployments with default credentials. Establish a regular patch and configuration review cycle.
- Baselines: Update your security baseline to require strong, unique passwords for all administrator accounts.
- Pipelines: Add static analysis tools to your CI/CD pipeline that detect the use of default credentials in configuration files.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Incorrect password entry may lead to account lockout.
- Roll back: Restore the SolarWinds Log and Event Manager configuration from the pre-change backup.
