Unintended Require in larvitbase-api

High severity GitHub Reviewed Published Sep 11, 2019 to the GitHub Advisory Database • Updated Sep 11, 2023

Package

npm larvitbase-api (npm)

Affected versions

< 0.5.5

Patched versions

0.5.5

Description

Versions of larvitbase-api prior to 0.5.4 are vulnerable to an Unintended Require. The package exposes an API endpoint and passes a GET parameter unsanitized to an require() call. This allows attackers to execute any .js file in the same folder as the server is running.

Recommendation

Upgrade to version 0.5.4 or later.

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.
