Arbitrary Code Injection

Affecting kmc package, ALL versions

Overview

kmc is a NodeJS-based KISSY module packaging tool that is currently available for KISSY 1.2+ code package.

Affected versions of the package are vulnerable to Arbitrary Code Injection due to unsafe use of the eval() function. Node.js provides the eval() function by default, and is used to translate strings into Javascript code. An attacker can craft a malicious payload to inject arbitrary commands.

Remediation

There is no fix version for kmc.
