Official description

The School Management System for Wordpress plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 93.0.0. This is due to the plugin not properly validating a user's identity prior to updating their details like email and password through the mj_smgt_update_user() and mj_smgt_add_admission() functions, along with a local file inclusion vulnerability. This makes it possible for authenticated attackers, with student-level access and above, to change arbitrary user's email addresses and passwords, including administrators, and leverage that to gain access to their account. This was escalated four months ago after no response to our initial outreach, yet it still vulnerable.

The underlying weakness: Missing Authentication for Critical Functionality

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

How developers prevent this class of flaw

  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
  • When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
