UserInputs dictionary results in Unbounded resource consumption in nodeJS

Moderate
MrWook published GHSA-38hx-x5hq-5fg4 Jun 7, 2023

Package

npm @zxcvbn-ts/core (npm)

Affected versions

< 3.0.2

Patched versions

3.0.2

Description

Impact

This is mainly for nodejs processes which are using the second argument of the zxcvbn function. It can result in an unbounded resource consumption as the user inputs array is extended with every function call.
Browsers are impacted, too but a single user need to do a lot of input changes so that it affects the browser, while the node process gets the inputs of every user of a platform and can be killed that way.

Patches

The problem is patched in version 3.0.2

Workarounds

Stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function

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.
