1. Introduction
Checkbox Survey is a web application used for creating surveys that has been detected on your network. This indicates a potential exposure point for attackers, as web applications are common targets. Successful exploitation could lead to data breaches and service disruption. Confidentiality, integrity, and availability may be impacted.
2. Technical Explanation
Checkbox Survey was detected during routine scanning of the remote host. If HTTP basic authentication or digest credentials are supplied, an attempt will be made to retrieve version information from its API. This allows for identification of potentially vulnerable instances.
- Root cause: The presence of the Checkbox Survey application on a system.
- Exploit mechanism: While no specific exploit is known at this time, attackers may target exposed web applications like Checkbox Survey to gain access or compromise data.
- Scope: Systems running the Checkbox Survey web application are affected.
3. Detection and Assessment
Confirming the presence of Checkbox Survey indicates a potential risk requiring investigation. Use the following methods to assess your systems.
- Quick checks: Access the Checkbox Survey URL in a web browser to confirm its presence.
- Scanning: Nessus plugin ID 16728 can detect Checkbox Survey installations. This is an example only and may require updates.
- Logs and evidence: Review web server logs for requests related to the Checkbox Survey application.
4. Solution / Remediation Steps
The following steps outline how to address the presence of Checkbox Survey on your systems.
4.1 Preparation
- Ensure you have a rollback plan in case of issues, such as restoring from backup.
- Consider a change window and obtain appropriate approvals.
4.2 Implementation
- Step 1: Determine the purpose of Checkbox Survey on your network.
- Step 2: If no longer needed, uninstall or remove the application from the server.
- Step 3: If required, ensure the application is running behind appropriate security controls (firewall, intrusion detection/prevention system).
4.3 Config or Code Example
No config or code changes are needed for removal.

- Re-test: Re-run the initial detection methods (Nessus scan) to confirm the application is no longer detected.
- Smoke test: Verify that other web applications on the server are functioning as expected.
- Monitoring: Monitor web server logs for any unexpected activity related to Checkbox Survey.
6. Preventive Measures and Monitoring
Implement preventive measures to reduce the risk of similar exposures in the future.
- Baselines: Update security baselines to include a list of approved applications on your network.
- Pipelines: Implement application whitelisting or blacklisting in CI/CD pipelines.
- Asset and patch process: Maintain an accurate inventory of all software assets and establish a regular review cycle.
7. Risks, Side Effects, and Roll Back
Removing Checkbox Survey may disrupt any processes that rely on it.
- Roll back: Restore from backup if necessary, or reinstall the application and its dependencies.
