1. Introduction
ViArt Shop Detection identifies instances of the ViArt Shop PHP shopping cart application running on a web server. This matters because publicly exposed applications can be targets for attackers seeking to exploit known vulnerabilities in the software. Affected systems are typically those hosting e-commerce websites using the ViArt Shop platform. A successful attack could compromise confidentiality, integrity and availability of customer data and website functionality.
2. Technical Explanation
The vulnerability lies in the presence of the ViArt Shop application itself. Attackers can identify and target known vulnerabilities within the software to gain unauthorized access or control. Exploitation requires network connectivity to the web server hosting the application. While no specific CVE is currently associated with simple detection, older versions are known to have security flaws. An attacker could attempt to exploit a SQL injection vulnerability in a search form to retrieve sensitive data from the database.
- Root cause: The ViArt Shop application is installed and accessible via the network.
- Exploit mechanism: Attackers scan for the presence of the application, then probe for known vulnerabilities such as SQL injection or cross-site scripting (XSS).
- Scope: Web servers running ViArt Shop PHP shopping cart application. Affected versions are not specified in this report.
3. Detection and Assessment
Confirming the presence of ViArt Shop can be done quickly through web server inspection. A more thorough assessment involves examining the application’s files and configuration.
- Quick checks: Access the website in a browser and look for branding or unique features associated with ViArt Shop. Check the robots.txt file for clues about the application structure.
- Scanning: Nessus plugin ID 16359 can identify ViArt Shop installations, but results should be verified manually.
- Logs and evidence: Web server access logs may show requests to specific ViArt Shop files or directories (e.g., /includes/, /admin/).
curl -I https://example.com/includes/ | grep "Server:"4. Solution / Remediation Steps
The primary solution is to ensure the ViArt Shop application is up-to-date or, if no longer needed, removed from the server.
4.1 Preparation
- Ensure you have access to the ViArt Shop installation files and database credentials. A roll back plan involves restoring the backups if issues occur.
- A change window may be required depending on the size of the website and potential downtime. Approval from the application owner is recommended.
4.2 Implementation
- Step 1: Download the latest version of ViArt Shop from the official website (https://www.viart.com/).
- Step 2: Back up the existing ViArt Shop installation directory.
- Step 3: Replace the existing files with the new version, ensuring file permissions are correct.
- Step 4: Run any database upgrade scripts provided with the new version.
- Step 5: Restart the web service.
4.3 Config or Code Example

Several security practices can mitigate risks associated with web applications like ViArt Shop.
- Practice 1: Patch cadence – Regularly update the application to address known vulnerabilities.
- Practice 2: Input validation – Implement strict input validation on all user-supplied data to prevent injection attacks.
4.5 Automation (Optional)
# Example Bash script for automated download and extraction - use with caution!
wget https://www.viart.com/downloads/latest_version.zip
unzip latest_version.zip -d /var/www/viartshop/
# Verify file integrity after extraction before restarting the web server.5. Verification / Validation
Confirming the fix involves verifying the updated version and performing a basic smoke test of the application’s functionality.
- Post-fix check: Access the website in a browser and confirm the ViArt Shop version has been updated (check ‘About’ page or similar).
- Re-test: Re-run the Nessus scan to verify the vulnerability is no longer detected.
- Smoke test: Test key user actions such as browsing products, adding items to the cart, and completing a purchase.
- Monitoring: Monitor web server logs for any unusual activity or errors related to ViArt Shop.
curl -I https://example.com/includes/ | grep "Server:" #Check version information in headers6. Preventive Measures and Monitoring
Implementing preventative measures can reduce the risk of future vulnerabilities.
- Baselines: Update security baselines to include regular patching requirements for web applications like ViArt Shop.
- Asset and patch process: Establish a documented asset inventory and patch management process with a defined review cycle.
7. Risks, Side Effects, and Roll Back
Updating ViArt Shop may introduce compatibility issues or require configuration changes.
- Roll back: Restore the web server and database from the pre-update backups.
