Description

Impact

What kind of vulnerability is it? Who is impacted?

Command Injection vulnerabilities in electerm:

A command injection vulnerability exists in github.com/elcterm/electerm/npm/install.js:130. The runLinux() function appends attacker-controlled remote version strings directly into an exec("rm -rf ...") command without validation.

Who is impacted: Users who run npm install -g electerm in Linux. An attacker who can control the remote release metadata (version string or release name) served by the project's update server could execute arbitrary system commands, tamper local files, and escalate compromise of development/runtime assets.

Patches

Has the problem been patched? What versions should users upgrade to?

Fixed in 59708b38c8a52f5db59d7d4eff98e31d573128ee, user no need to upgrade, the new version already published in npm

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 a Command ('Command Injection')

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