1. Introduction
SolarWinds Storage Manager Detection indicates that a web-based storage management application is running on the remote host. This application manages storage resources and presents an attack surface to potential attackers. Affected systems are typically those used for central storage administration within businesses, potentially impacting confidentiality, integrity, and availability of stored data.
2. Technical Explanation
The vulnerability lies in the presence of SolarWinds Storage Manager on a system accessible from a network. While not an inherent flaw in the application itself, its detection flags a potential risk due to past security incidents associated with SolarWinds products. An attacker could exploit known vulnerabilities within the application or use it as a foothold for further compromise. The main precondition is network accessibility to the web interface.
- Root cause: Presence of the SolarWinds Storage Manager application on the host.
- Exploit mechanism: An attacker would attempt to access and exploit known vulnerabilities within the SolarWinds Storage Manager web application, potentially leading to remote code execution or data theft.
- Scope: Systems running any version of SolarWinds Storage Manager are affected.
3. Detection and Assessment
Confirming the presence of SolarWinds Storage Manager can be done through several methods. A quick check involves looking for the application’s web interface in a browser or checking running processes.
- Quick checks: Access the system’s web services via a browser, looking for a login page associated with SolarWinds Storage Manager.
- Scanning: Nessus vulnerability ID 168947 can detect this application. This is an example only and may require updated plugins.
- Logs and evidence: Review web server logs for requests to paths commonly used by SolarWinds Storage Manager, such as /StorageManager/.
netstat -an | grep 80 or netstat -an | grep 4434. Solution / Remediation Steps
The primary solution is to assess the need for SolarWinds Storage Manager and, if not required, remove it. If necessary, ensure it’s patched and hardened.
4.1 Preparation
- Ensure you have access to the SolarWinds Storage Manager installation media or download location for re-installation if needed. A roll back plan involves restoring from the pre-change backup.
- Change windows may be required depending on service impact, and approval should be obtained from IT management.
4.2 Implementation
- Step 1: If SolarWinds Storage Manager is not required, uninstall it using the standard Windows Add or Remove Programs control panel.
- Step 3: If SolarWinds Storage Manager is required, check for available updates on the SolarWinds website and install them following their documentation.
4.3 Config or Code Example
This vulnerability does not involve a specific configuration error; it relates to the presence of the application itself.
Before
SolarWinds Storage Manager is installed and running.After
SolarWinds Storage Manager is uninstalled or updated to the latest version.4.4 Security Practices Relevant to This Vulnerability
Several security practices can help mitigate risks associated with applications like SolarWinds Storage Manager.
- Practice 1: Least privilege – limit user access to only those resources required for their role, reducing the impact of a potential compromise.
- Practice 2: Patch cadence – regularly update all software, including storage management applications, to address known vulnerabilities.
4.5 Automation (Optional)
Automated removal can be done via PowerShell scripting, but requires careful testing.
# Example PowerShell script - use with caution!
Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*SolarWinds Storage Manager*"} | Uninstall-Package5. Verification / Validation
Confirm the fix by verifying that SolarWinds Storage Manager is no longer present or has been updated to a secure version.
- Post-fix check: Run `netstat -an | grep 80` and `netstat -an | grep 443`. There should be no listening ports associated with the application.
- Re-test: Re-run the Nessus scan (ID 168947) to confirm it no longer detects SolarWinds Storage Manager.
- Monitoring: Monitor web server logs for any unexpected requests related to SolarWinds Storage Manager, indicating a potential re-installation attempt. This is an example only.
netstat -an | grep 806. Preventive Measures and Monitoring
Preventative measures include maintaining accurate software inventories and implementing regular vulnerability scanning.
- Baselines: Update a security baseline or policy to reflect approved software lists, preventing unauthorized installations like SolarWinds Storage Manager.
- Pipelines: Add checks in CI/CD pipelines to scan for known vulnerabilities in deployed applications.
- Asset and patch process: Implement a regular patch review cycle to ensure timely updates of all installed software.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Service disruption – uninstalling a critical application can impact storage availability; mitigate by careful planning and testing.
- Roll back: Restore the system from the pre-change backup if issues occur during uninstallation or update.
