Official description

The Bot for Telegram on WooCommerce plugin for WordPress is vulnerable to sensitive information disclosure due to missing authorization checks on the 'stm_wpcfto_get_settings' AJAX action in all versions up to, and including, 1.2.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the Telegram Bot Token, a secret token used to control the bot, which can then be used to log in as any existing user on the site, such as an administrator, if they know the username, due to the Login with Telegram feature.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
