cruddl vulnerable to ArangoDB Query Language (AQL) injection through flexSearch

Critical severity GitHub Reviewed Published Sep 8, 2022 in AEB-labs/cruddl • Updated Jan 27, 2023

Package

npm cruddl (npm)

Affected versions

>= 3.0.0, < 3.0.2
>= 1.1.0, < 2.7.0

Patched versions

3.0.2
2.7.0

Description

Impact

If a vunerable version of cruddl is used to generate a schema that uses @flexSearchFulltext, users of that schema may be able to inject arbitrary AQL queries that will be forwarded to and executed by ArangoDB.

Schemas that do not use @flexSearchFulltext are not affected.

The attacker needs to have READ permission to at least one root entity type that has @flexSearchFulltext enabled.

Patches

The issue has been fixed in version 3.0.2 and in version 2.7.0 of cruddl.

Workarounds

Users can temporarily remove @flexSearchFulltext from their schemas before they can update cruddl.

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.
