User Profile Builder: Incorrect Authorization
CVE-2024-6695 is a critical-severity incorrect authorization vulnerability in User Profile Builder, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 3.11.9 as the first without the flaw, so updating User Profile Builder to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.75% chance of exploitation within 30 days, higher than 86% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update User Profile Builder to 3.11.9 or a later version.
- Update profile_builder to 3.11.9 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
it's possible for an attacker to gain administrative access without having any kind of account on the targeted site and perform unauthorized actions. This is due to improper logic flow on the user registration process.

The underlying weakness: Incorrect Authorization
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
How developers prevent this class of flaw
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
- Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.
- 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 authorization frameworks such as the JAAS Authorization Framework and the OWASP ESAPI Access Control feature.
