Command Injection in node-rules

High severity GitHub Reviewed Published Sep 3, 2020 to the GitHub Advisory Database • Updated Oct 6, 2023

Package

npm node-rules (npm)

Affected versions

< 5.0.0

Patched versions

5.0.0

Description

Versions of node-rules prior to 5.0.0 are vulnerable to Command Injection. The package fails to sanitize input rules and passes it directly to an eval call when using the fromJSON function. This may allow attackers to execute arbitrary code in the system if the rules are user-controlled.

Recommendation

Upgrade to version 5.0.0 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.

Weaknesses

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Learn more on MITRE.
