Directus vulnerable to extraction of password hashes through export querying

Moderate severity GitHub Reviewed Published Mar 7, 2023 in directus/directus • Updated Mar 26, 2023

Package

npm directus (npm)

Affected versions

< 9.16.0

Patched versions

9.16.0

Description

Impact

Users with read access to the password field in directus_users can extract the argon2 password hashes by brute forcing the export functionality combined with a _starts_with filter. This allows the user to enumerate the password hashes.

Patches

The problem has been patched by preventing any hashed/concealed field to be filtered against with the _starts_with or other string operator.

Workarounds

Ensuring that no user has read access to the password field in directus_users is sufficient to prevent this vulnerability.

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.
