1. Introduction
X-Cart Concierge Module Information Disclosure refers to a vulnerability where sensitive information about an X-Cart installation is exposed through the Concierge module. This can allow attackers to gather details needed for further attacks, potentially compromising store data and customer information. Affected systems are typically e-commerce stores running the X-Cart platform with the Concierge module enabled. A successful exploit could lead to loss of confidentiality, integrity, and availability.
2. Technical Explanation
The X-Cart Concierge module can unintentionally expose administrative details. This occurs because the module may not adequately restrict access to sensitive configuration data. An attacker with network access can potentially retrieve information such as the admin account email address, company name, and license type. There is no known CVE associated with this specific issue but it’s related to insecure configurations.
- Root cause: Insufficient restriction of access to administrative module data.
- Exploit mechanism: An attacker sends a request to the Concierge module endpoint, retrieving exposed configuration information. For example, accessing a specific URL associated with the module’s admin interface.
- Scope: X-Cart installations using the Concierge module are affected. Specific versions were not identified in available documentation.
3. Detection and Assessment
To confirm vulnerability, check if the Concierge module is installed. Then, attempt to access its configuration data directly through a web request.
- Quick checks: Access the X-Cart admin interface and navigate to Modules. Check for the presence of the “Concierge” module.
- Scanning: Nessus or OpenVAS may identify this issue with appropriate plugins enabled, but results should be verified manually.
- Logs and evidence: Review web server access logs for requests targeting Concierge module endpoints. Look for unusual activity or attempts to access configuration files.
# No specific command available; check X-Cart admin interface directly.4. Solution / Remediation Steps
The primary solution is to disable the Concierge module if it’s not required, or restrict access to the admin page.
4.1 Preparation
- No services need to be stopped for this remediation.
- Roll back plan: Re-enable the Concierge module if disabling causes functionality issues.
4.2 Implementation
- Step 1: Log in to your X-Cart admin panel.
- Step 2: Navigate to Modules & Services.
- Step 3: Locate the Concierge module and disable it. Alternatively, restrict access to the admin interface using IP address filtering or authentication controls.
4.3 Config or Code Example
Before
# Concierge module enabled with unrestricted access. (Admin interface screenshot showing active module)After
# Concierge module disabled. (Admin interface screenshot showing inactive module) or admin page access restricted via firewall/access control list. 4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this issue.
- Practice 1: Least privilege – Limit user and service account permissions to the minimum required for operation, reducing potential impact if compromised.
- Practice 2: Secure configuration – Regularly review and harden system configurations to remove unnecessary features or services and enforce strong security settings.
4.5 Automation (Optional)
No automation is available at this time.
5. Verification / Validation
Confirm the fix by verifying that sensitive information is no longer accessible through the Concierge module endpoint.
- Post-fix check: Attempt to access the Concierge module’s configuration data via a web request. You should receive an error or restricted access message.
- Re-test: Repeat the detection steps from Section 3; the module should no longer expose sensitive information.
- Monitoring: Review web server access logs for any attempts to access Concierge module endpoints and alert on unexpected activity.
# No specific command available; test via web request as described above.6. Preventive Measures and Monitoring
Regular security assessments and configuration reviews can help prevent similar vulnerabilities.
- Baselines: Implement a security baseline for X-Cart installations, including module restrictions and access controls.
- Asset and patch process: Maintain an inventory of installed modules and regularly review their security status.
7. Risks, Side Effects, and Roll Back
Disabling the Concierge module may affect related functionality if it’s actively used.
- Roll back: Re-enable the Concierge module in the X-Cart admin panel to restore its functionality.
