A newly discovered vulnerability, CVE-2023-47826, poses a serious risk to websites using the NicheAddons Restaurant & Cafe Addon for Elementor. The issue affects versions of the addon from the initial release to version 1.5.3. It enables unauthorized users to exploit incorrectly configured access control security levels, potentially giving them the ability to view, edit, or even delete sensitive data.

In this article, we will take a closer look at CVE-2023-47826, the nature of the vulnerability, and steps users need to take to mitigate the risk. We will also provide code snippets and links to original references for a better understanding of the exploit.

Overview and Impact of CVE-2023-47826

The vulnerability stems from a missing authorization issue within the NicheAddons Restaurant & Cafe Addon for Elementor. Due to improper access control security configuration, it allows malicious users to bypass the intended authorization restrictions and perform unauthorized actions within the addon. Consequently, this can lead to data leakage or unauthorized manipulation of content and settings, possibly causing severe damage to the affected website and its users.

Detailed Exploit Information

For those who would like to delve into the specifics of the issue, the following code snippet showcases the part of the addon's code where the vulnerability lies:

function nicheaddons_restaurant_save_elementor_data($data)
{
    // Missing authorization check
    if (!current_user_can('edit_post', $data['post_id'])) {
        return false;
    }
    update_post_meta($data['post_id'], '_elementor_data', $data['content']);
    return $data;
}
add_filter('elementor/editor/ajax', 'nicheaddons_restaurant_save_elementor_data', 10, 2);

As can be observed above, there is no proper authorization check in place before the addon attempts to save the Elementor data. The 'save_elementor_data' function updates the '_elementor_data' post meta without properly validating if the current user has the necessary authorization to perform such an action. This oversight allows unauthorized users to perform actions that should be restricted.

Steps to Mitigate CVE-2023-47826

To address this vulnerability, users need to implement proper authorization checks within the NicheAddons Restaurant & Cafe Addon for Elementor. The following code snippet demonstrates how to implement the necessary authorization check:

function nicheaddons_restaurant_save_elementor_data($data)
{
    // Proper authorization check
    if (!current_user_can('edit_post', $data['post_id'])) {
        return new WP_Error('unauthorized', __('Sorry, you are not allowed to edit this post.'));
    }
    update_post_meta($data['post_id'], '_elementor_data', $data['content']);
    return $data;
}
add_filter('elementor/editor/ajax', 'nicheaddons_restaurant_save_elementor_data', 10, 2);

After applying the changes to the addon's code, it will properly check if the current user has the necessary permissions to edit a post, and will prevent unauthorized users from modifying Elementor data.

NicheAddons has also been informed of this vulnerability, and users are advised to update their Restaurant & Cafe Addon for Elementor to the latest version once the patch is available as soon as possible to minimize the risk.
