Wpvivid — Backup, Migration & Staging

The WPvivid Backup & Migration plugin for WordPress is vulnerable to SQL Injection via the export_data parameter in versions up to, and including, 0.9.131. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The values are received in prepare_export_post(), passed through sanitize_text_field() and stripslashes(), JSON-decoded, and the attacker-controlled JSON object keys are collected as $posts_ids without integer casting. They are stored in the export task options and later joined with commas and interpolated directly into a `WHERE ID IN (...)` clause inside a $wpdb->get_results() call in export_post_to_xml() (unquoted, numeric context), with no $wpdb->prepare() or esc_sql(). This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Upload in versions up to and including 0.9.123. This is due to improper error handling in the RSA decryption process combined with a lack of path sanitization when writing uploaded files. When the plugin fails to decrypt a session key using openssl_private_decrypt(), it does not terminate execution and instead passes the boolean false value to the phpseclib library's AES cipher initialization. The library treats this false value as a string of null bytes, allowing an attacker to encrypt a malicious payload using a predictable null-byte key. Additionally, the plugin accepts filenames from the decrypted payload without sanitization, enabling directory traversal to escape the protected backup directory. This makes it possible for unauthenticated attackers to upload arbitrary PHP files to publicly accessible directories and achieve Remote Code Execution via the wpvivid_action=send_to_site parameter.

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'wpvivid_upload_import_files' function in all versions up to, and including, 0.9.116. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: Uploaded files are only accessible on WordPress instances running on the NGINX web server as the existing .htaccess within the target file upload folder prevents access on Apache servers.

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary directory deletion due to insufficient file path validation in the delete_cancel_staging_site() function in all versions up to, and including, 0.9.128. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary folders on the server, which leads to a loss of data.

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary directory creation in all versions up to, and including, 0.9.120. This is due to the check_filesystem_permissions() function not properly restricting the directories that can be created, or in what location. This makes it possible for authenticated attackers, with Administrator-level access and above, to create arbitrary directories.
