How to Detect?

To detect if the WPMobile.App plugin is affected, navigate to the Plugins page within the WordPress administration panel. Locate the WPMobile.App plugin and check its installed version number.

For Linux/Windows environments with WordPress CLI (wp) installed, use the following command:

wp plugin list --field=version --format=csv | grep wpmobile.app

This command lists plugin versions and filters for `wpmobile.app` to display the installed version. If `wp` is not available in the system’s PATH, provide the full path to the `wp` executable.

**How to Mitigate?**

  1. Update the Plugin: Update the WPMobile.App plugin to version 11.57 or higher.
  2. Temporary Mitigation: If updating is not immediately possible, disable the plugin until an update can be applied. Implement input validation for the ‘redirect’ parameter as a temporary measure.

**Mitigation Commands for Linux Environments**:

  • Update via Composer: If the plugin was installed via Composer, use the following command:
    composer update wpmobile.app
  • Disable the Plugin: Use the WordPress CLI to disable the plugin temporarily:
    wp plugin deactivate wpmobile.app

**What Undercode Say**

The CVE-2024-13888 vulnerability in the WPMobile.App plugin highlights the importance of maintaining up-to-date software in WordPress environments. Regularly updating plugins and themes is a critical step in securing your website. For Linux users, leveraging command-line tools like `wp` and `composer` can streamline the update process and ensure compliance with security best practices.

To further enhance security, consider implementing the following Linux commands to monitor and harden your WordPress installation:
1. Check File Permissions: Ensure WordPress directories and files have the correct permissions:

find /var/www/html -type d -exec chmod 755 {} \;
find /var/www/html -type f -exec chmod 644 {} \;

2. Audit Logs: Regularly review Apache or Nginx logs for suspicious activity:

tail -f /var/log/apache2/access.log

3. Install a Firewall: Use `ufw` to configure a firewall and restrict unnecessary access:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable

4. Automate Updates: Set up a cron job to automatically update WordPress core and plugins:

0 3 * * * /usr/bin/wp core update --path=/var/www/html
0 4 * * * /usr/bin/wp plugin update --all --path=/var/www/html
