Low
dpgaspar published GHSA-9hcr-9hcv-x6pv Apr 10, 2023

Package

pip Flask-AppBuilder (pip)

Affected versions

<4.3.0

Patched versions

4.3.0

Description

Impact

Lack of rate limiting will allow an attacker to brute-force user credentials

Patches

Ability to enable rate limiting on Flask-AppBuilder >= 4.3.0. Use AUTH_RATE_LIMITED = True and RATELIMIT_ENABLED = True set the limit itself by using AUTH_RATE_LIMIT more details on https://flask-limiter.readthedocs.io/en/stable/configuration.html. Will apply only to database authentication.

Workarounds

Implement rate limiting using a reverse proxy or other strategies.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
