Flask-AppBuilder before v4.1.3 allows inference of sensitive information through query strings

Low severity GitHub Reviewed Published Jul 28, 2022 in dpgaspar/Flask-AppBuilder • Updated Jan 30, 2023

Package

pip Flask-AppBuilder (pip)

Affected versions

< 4.1.3

Patched versions

4.1.3

Description

Impact

An authenticated Admin user could craft HTTP requests to filter users by their salted and hashed passwords strings. These filters could be made by using partial hashed password strings. The response would not include the hashed passwords, but an attacker could infer partial password hashes and their respective users.

Only when using AUTH_DB database authentication option.

Patches

Fixed on 4.1.3

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.
