SiteGuard WP Plugin provides a functionality to customize the path to the login page wp-login.php and implements a measure to avoid redirection from other URLs. However, SiteGuard WP Plugin versions prior to 1.7.7 missed to implement a measure to avoid redirection from wp-register.php. As a result, the customized path to the login page may be exposed.
Weakness
The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
Potential Mitigations
- 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.
