Arbitrary File Write in iobroker.js-controller

High severity GitHub Reviewed Published Dec 2, 2019 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm iobroker.js-controller (npm)

Affected versions

< 2.0.25

Patched versions

2.0.25

Description

Versions of iobroker.controller prior to 2.0.25 are vulnerable to Path Traversal. The package fails to restrict access to folders outside of the intended /adapter/<adapter-name> folder, which may allow attackers to include arbitrary files in the system. An attacker would need to be authenticated to perform the attack but the package has authentication disabled by default.

Recommendation

Upgrade to version 2.0.25 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.
